The male talent pool for penetrative cinema is disparagingly smaller than you might think. (I've been desiring to supplement my income through such libidinous means for years now.) I would be surprised if she's actually handled in excess of 200 various dicks in her on-screen career.
Jenna is kind of like Metallica - we might not like what's become of them, but their early body of work cannot be denied. Jenna's performance in Satyr is truly timeless and the scene where her precious puckered smucker so lovingly receives that glass dildo at Missy's tender behest has me fapping 13+ years on.
