In some way having a label makes gay sex easier because everyone knows what to do. But the problem is that tops are almost always seen as more manly, virile, and aggressive, whereas bottoms are usually linked to effeminacy because we think they have a subservient position. Just don’t tell the power bottoms that.
People are obsessed with knowing who is the top and who is the bottom because gay sex is not necessarily legible in the same manner as straight sex. How many times have you been dating a new guy and you voluntarily told your BFF, “He’s a TOTAL TOP” or “He’s a great bottom,” or how many times have your friends asked you what was going on in the bedroom between you and a new love interest?
Hey, there are plenty of folks out there who don’t like bottoming and even some who don’t like to top. Why? Because gay sex is only legible to straight people in terms of the heterosexual matrix, and if someone’s son is fucking a dude/is a top, well then that’s way preferable than if he was getting plowed by D’s all day long.
This attitude is wholly cultural and deeply rooted in how we think about gender. Like, men are supposed to be men. Like, men don’t take dicks up the ass.
