check out my possessive yaoi list
http://www.mangago.me/home/mangalist/14959/
i don`t like cheating in yaoi and since i only collect mangas i like for my lists so my possessive yaoi list is without cheating^^
maybe you wanna leave out:
the 2nd story of number 36 though (the uke is in a relationship with a married man when he mets the seme)
number 40 (at the beginning the seme still sleeps with others, though he is not together with the uke then)
rarely, but happens sometimes to me too^^
as long as they`re not together yet...
but normally i just get angry, when i read a manga about a cheater i hope that his lover leaves him
last time i read a yaoi where the uke pitied a lonely guy who is in love with him thus allows him to sleep with him - and i thought wtf? what about your loved and loving seme waiting for you? you`re not thinking about him at all!
so yeah...
well, everyone has his own preferences^^
is there any yaoi manga that the couple is faithful and possesive to each other?
