I might just be over thinking this but....

idek ╮(￣▽￣)╭

thats what i want to know too ╥﹏╥

The most reluctant one wins. That's usually how it is in yaoi.

╮(￣▽￣)╭ I don't care as long as it's steamy, they can make it reversible as well and I wont mind.

I think irl most gay couples do both, unlike manga

in bl or yaoi it has more stereotyped like big and buff are tops and the reverse are bottoms, but irl it depends on the couple.

Or they talk about who can do who. Some are only bottoms and some are only tops so it would prob be a conversation. Unless there is an obvious more dominant one and the submissive one doesn’t object.

Aren't there also dominant uke and puppy seme? (￣∇￣")

In most of the ones I read its usually the bigger guys so I'm really curious about guys with similar builds(⌒▽⌒)

it's not decided. it just is. if you're taller and have some muscle mass, you are top. no exceptions
