Hmm
I think there could be multiple reasons for this.
1. Most men have hairy asses.
2. The homo issue, Most manly men are afraid like stated earlier if I really like this, does it mean im gay.
3. Its my ass, if a man has done his girl anally before and sees how much it hurts at first, i doubt he is going to want to do it.
4. Talking, I know If word got out about me letting my girl do me with a strapon, the shit talking, and teasing would never end. Like if you break up, she runs her mouth, small town, people talk, you are a freak, maybe people call you gay as well.
5. Im 6'2 225lbs around 9-11% bodyfat, and I take 2-3 shits a day eating as many calories as I can, am I supposed to time bowel movements around this?
6. Im 6'2 225lbs, I cant picture myself laying down, putting my legs in the air so I can have my salad tossed.
Those are some ideas, im sure some can relate.
I dont mind if my girl rubs my pernemium, the spot bewteen my ass and my balls, thats all good and fun, but Im not comfortable with her near my ass.
