illuminaughty's Things

I've always been wondering this, how accurate are sex scenes in yaoi manga, is the real life thing similar to it or are there certain things that are exaggerated and never really happen/don't happen that way in real life?
as for me idk i guess they're not always as aggressive...probably not all of them lick buttholes/nipples... but i wouldn't know though after all I'm just a bisexual female lmao
