Jokingly, it seems that many men don’t grasp nor believe that women use their anus to defecate.
Anal- ‘sex,’ physiologically, and scientifically: is a damaging, unsanitary, and unnatural; occurrence, at acute-observance.
Sadistically, and perversely: this seems to be why it such an arcane sexual-fetish, for men, to insert their penis into the rectum of a woman.
True, but it can still be an enjoyable sexual experience for many. However, I do want to stress that people should read-up on it before trying it.
Myself, I wouldn't force it on any woman. If she wants, I'll give it to her. Statistically though, the percentage of women who want anal sex is quite low. Odd thing is, I meet women that like anal sex as well as vaginal. That's just chance occurrances though.
On another subject, and this is a bit amusing, is to see your avatar all ass bare waiting to get...well...ahum...let's leave it to the imagination.
And, isn't the porn star in your avatar, if I'm not mistaken, does venture into anal sex?
Overall, my message to anyone out there into anal sex: please, take your precautions and use proper technique.
