Defendant, Garfield Hollis, was convicted by a jury of first-degree criminal sexual conduct, in violation of MCL 750.520b; MSA 28.788(2). After being sentenced to life imprisonment, he appeals as of right.

Defendant first alleges that there was not sufficient evidence to sustain his conviction on the charged offense. In People v Johnson,1 this Court set forth the standard to be followed where a claim is made that the evidence is insufficient upon which to find guilt:

"Would the evidence presented by the prosecution justify a reasonable person in concluding that all elements of the crime were established beyond a reasonable doubt?”

In this case, the complainant did not visually see the act of oral contact which would constitute penetration under the statute, but testified in terms of the physical sensations he experienced. Defendant contends that such testimony is insufficient to support a finding of penetration. We disagree. The elements of a criminal offense may be *337proved by circumstantial evidence and the reasonable inferences arising therefrom.2

In People v Palmer,3 the Supreme Court noted that:

"It is the function of the jury alone to listen to testimony, weigh the evidence and decide the questions of fact. People v Mosden, 381 Mich 506, 510; 164 NW2d 26 (1969). In determining the facts the jury may draw reasonable inferences from the facts established by either direct or circumstantial evidence. People v Weyonen, 247 Mich 308, 311; 225 NW 552 (1929).”

The fact that the complainant did not witness the actions of the defendant at the moment of penetration does not render the evidence insufficient where the circumstances of the assault and the graphic description of physical sensations strongly point to the achievement of penetration. We find ample evidence to establish this element of the offense.

Defendant’s argument that the prosecution did not establish the element of "personal injury” under the sexual assault statute likewise fails under the facts of the case. The complainant testified that defendant forcefully grabbed him around the neck and pushed him onto the bed immediately prior to the assault. Complainant suffered bruises and scratches which were evidenced by photographic documentation. We believe that such bruising, caused by the forceful application of a hand, constitutes personal injury within the meaning of the applicable statutory definition.4 We con-*338elude that there was sufficient evidence to meet the Johnson standard.

Second, defendant alleges that the trial court abused its discretion in denying defendant’s motion to suppress evidence of his prior criminal record.

In this case, the 76-year-old defendant moved to suppress any reference to his eight previous felony convictions. The sentence for the last such felony was enhanced when defendant was convicted on a supplemental information as an habitual offender in 1956.5 The trial court suppressed reference to four felonies, three CCW’s and a larceny over $100, but indicated if defendant testified, he could be impeached by reference to the other four felonies, robbery with physical harm in 1932, assault with intent to commit unarmed robbery in 1950, indecent liberties with a minor child in 1951, and unarmed robbery in 1955.6 Faced by this ruling, the defendant, understandably, chose not to testify.

On appeal, defendant claims the trial court’s ruling constituted an abuse of discretion. We find, contrary to the argument of defendant, that the trial court adequately articulated on the record the reasons for exercising its discretion in allowing the use of evidence of the prior convictions.7 We note that, in this regard, the discretion of the trial court is not unlimited. The fact that the trial judge states on the record that she is exercising her discretion does not preclude judicial review to determine whether there is an abuse of discretion.8

*339While this case was tried prior to March 1, 1978, the effective date of the Michigan Rules of Evidence, Rule 609 is helpful and instructive in indicating the direction of the Supreme Court’s thinking.9

If we were to apply Rule 609 here, there would be a threshold question of whether the time limit subsection would prohibit use of these felonies for purpose of impeachment,10 since all were committed more than 10 years ago.

However, for the 1955 conviction and enhanced sentence as an habitual offender in 1956, there is indication defendant continued to serve time in prison until 1968. As this would be less than 10 years before trial in 1977, Rule 609 would not necessarily, on that 10-year time limitation basis, prohibit use of evidence of the 1955 felony to impeach. Under Rule 609, the other three felonies concerning which the trial judge would have here permitted cross-examination by the prosecutor would not have been admissible.

Part of the reason for the 10-year limitation is to furnish protection to rehabilitated offenders from attacks on their credibility for youthful, or long-passed, felonious indiscretions. Obviously, that rationale does not apply to an eight-time offender whose convictions occur with regularity and extend over a 30-year period. As a matter of fact, this case poses the difficult question of how the rule should be applied in the case of a lifetime, career offender.

*340In addition, one of defendant’s previous felony convictions was for a sex offense, namely, indecent liberties with a minor child in 1951. Under People v Baldwin,11 similarity of offense is one factor militating against admissibility.

Applying the balancing test to whether or not to permit cross-examination of defendant concerning these four felonies, we hold that the probability of prejudice to defendant far outweighs its relevancy for purposes of determining credibility and that to permit cross-examination of defendant concerning these four felonies constituted an abuse of discretion. The transcript appears to indicate an issue concerning whether the victim consented to this homosexual act of penetration, a question which can best be resolved by a jury hearing both defendant and the victim. As a practical matter, a ruling which would permit extensive cross-examination of defendant regarding four previous felonies prevented defendant from testifying.

In the event of retrial, we would believe that, if defendant chooses to testify, the prosecution should be entitled to ask this defendant if he had ever been convicted of a felony.12 In this connection, the relevancy or admissibility of evidence of past convictions does not depend upon the degree of probability with which recidivists commit further felonies. Under the so-called bad guy rule, the Supreme Court has held such evidence inadmissible. The possibility of it becoming admissible only arises where a witness (defendant) places his credibility in issue. Even then, such evidence is now *341only admissible within the parameters of Rule 609. Consequently, we neither speculate nor rule as to what further inquiry, if any, could be permitted without unduly prejudicing the defendant.

Consistent with this analysis, we reverse defendant’s conviction and remand this case to the trial court.

Reversed and remanded.

(dissenting). I respectfully dissent from that portion of the majority opinion dealing with the inadmissibility of evidence of certain of the defendant’s prior convictions.

The trial judge did not have the new rules of evidence to follow at the time of this trial. What rules and case law were available she did follow very thoughtfully.

As the majority points out, the application of the provisions of Rule 6091 to a lifetime career offender may be difficult. The question is what to admit and what not to when credibility is placed at issue.

I would, however, point out that a lifetime career offender with a bedsheet record has very little credibility, if any. When such a witness takes the stand to tell his story, he should have other witnesses to substantiate that story, because his testimony alone usually isn’t believed, and understandably so.

I do not feel that the trial judge here abused her discretion in ruling that evidence of certain prior convictions was admissible on the question of credibility. She was very careful in her review and did exclude evidence of four of defendant’s eight prior convictions.

Although the majority opinion does not say that *342Rule 609 is retroactive, I believe that is its position. In any event, my position is that it is not. Court-made rules are not retroactive unless so designated.

I would affirm the conviction.
