Why is Yaoi so unrealistic..? I've never read a Yaoi manga where the couple is versatile. Not everyone is a strict bottom/top in real life. The top is not always the biggest muscledguy.. It almost feels like Yaoi wants to reproduce stereotypical heterosexual relationships. One of the great things about gay/lesbian relationships is that we can (re)invent and play with the norms and social roles..
if anyone knows of a versatile Yaoi couple, please recommend it here! Thanks
