I don't think anyone publicly asked him about sex lol. And he doesn't write about it in his novels, don't know if that is telling. I did watch a documentary where a lesbian decided to find out what it was like to be a man for several months. How she was surprised how accepting men where when she went to the bowling alley and got accepted into a group very quickly. And how they went to strip clubs together and she noticed that for men there didn't seem to be emotional attachment like women would have, it seemed more of a function that they had no control of. She did eventually start to struggle with some of the emotional side of trying to be a man without the kind of intimacy and emotional connection she was used to with female friends. Caused quite a few problems towards the end that came close to self harm. When they talked to her buddies about her. They were shocked that she was actually a woman but always figured that her male character was gay, which didn't bother them. Was quite interesting.
