Mindy McCready, Rogers Clemens’ one-time mistress, talks about the Rocket’s sexual prowess in an upcoming sex tape says RadarOnline.com.

Fox’s PopTarts reports that the tape features McCready and a former boyfriend named “Peter” engaging in explicit sex acts, but that in the video, McCready also kisses and tells about other partners, saying that Clemens was a “good” lover, although he often struggled to get an erection. She said that another celebrity she slept with, Superman actor Dean Cain, was better endowed than Clemens.

McCready also says in the video, she wishes her and Clemens’ wife Debbie “had spoken, because I realize now that the stories I was being told from Roger weren’t exactly the truth,” according to PopTarts.

Ya think? The dude was cheating on his wife – did you actually believe he was telling you the truth about anything?

None of this surprises me. Superman should have bigger junk than Roger Clemens – he’s a superhero for God’s sake. And isn’t one of the side effects of taking steroids the inability to, uh, launch your rocket?
