Juan - I think for straight guys it's part the taboo, and part the fact that.....how shall I put this.....things are a little more snug in that area, lol.
And I have to say - the prostate thing - I've always wondered about that. I can totally understand why guys would find it pleasurable, but for girls, is it ever actually GOOD? Or does it just become merely tolerable? B/c tolerable just isn't enough of a reason to grant backstage access, haha.
Have a great time Sheyne! You'll be missed!
And for the record, I didn't "deal" with anything in the shower, I swear, lol!
