Why do men like to have sex with a woman's ass?

Why?

Because it’s fun. That’s it. It’s enjoyable and feels good. It’s really not rocket science.

Throughout my life, until just recently, I’ve had girlfriends who enjoy receiving anal sex, and I’ve always been willing to do it, though I’ve never been a huge fan; too much work for something I personally didn’t find particularly interesting.^2

Can it be true that people know your name, not your story, they’ve heard what you’ve done, but not what you’ve been through, so take their opinions of you with a grain of salt?

1. Yes, I prefer underscore_notation to camelCase. It’s easier to read. Change my mind.

I now have a lover who is a passionate and enthusiastic fan of anal sex, and she has an ass that is…um, extraordinarily accommodating and a great deal of fun. So, for the first time in my life, I have a partner I actively enjoy giving anal sex to.^3

2. Giving, anyway. I’ve always been a big fan of receiving, which is why almost all my lovers have been quite skilled with a strapon, and I even own a patent on a new type of strapon.

What would happen if the Soviet Union had simply annexed Manchuria after World War 2 or kept it independent as a puppet state allied them and separate from China as China was too weak too oppose it anyway?

3. Yes, this does mean I’ll do things during sex I don’t necessarily actively enjoy myself. I think one of the hallmarks of a good lover is willingness to do things that get your partner hot even if they don’t necessarily rev your motor.

The answer to basically any question of the form “why do $people like $sex_thing”^1 is “because it’s fun.”
