Anal sex might be seen as gross or disturbing to some. But there are some of us who are so detached and numbed by things that it adds a level of excitement. I approve of both methods of anal sex:
1. Consensual anal sex. Meaning it's discussed and on her terms. She must be ok with it. No does, in this case, mean no.
2. Whoops! AKA. The Slip - NIN.
The surprise buttsecks can work in two ways. Either: You get slapped. She cries. She leaves. You never get to sleep with her again because you're gross and mean and a poopyhead. Also, your face is stupid.
Or.......
She likes it. You open the door to a brand new world of winzilla. It hurt at first, but with the right clitoral stimulation to get the juices flowing, you've helped open her eyes to a whole new dimension of orgasmic victory.
I encourage you to try either way. If option one fails you, you can always push for option two... especially if the relationship is almost done anyway. It could save it.
This brings me to my next point. Anal sex with a woman is awesome. Anal sex with a man is not. Here's why:
I have nothing against gay people. I have many gay friends. I get hit on by gay people often and have been propositioned by some. I take it as a compliment.
However, I feel bad for gay people. They are limiting their options here!
Women have three viable orifices to utilize. Men have two. It seems us straight guys are getting the better deal here.
Of course, if you also like getting pounded in the ass or like giving head, then you have four options, where us straight guys only have three (not including strapons... which is not my thing)
Of course, I cannot attest to the benefits of being fucked and/or giving head. So, I think straight guys win.
