yo I think you got what you said mixed up
Yaoi is gay anime/manga porn and shounen-ai is just gay anime/manga. It's been so long that I don't even remember this manga but I assume I commented this because, even though the manga is clearly marked yaoi, there are no sex scenes. So no, I do not have things mixed up.
it have a sex scene, they both naked and both are in bed. and he give him a blowjob
not every yaoi need to show alll the datelies.
this is still yaoi cause they have a bed scene, even if you don't have "all the scene" it not just porn.
besides most yaoi mange censor the dick and sex scenes a lott!! so you can't call it a real porn!
if you want porn, go watch live action gay porn.
at least there it won't have soo much censor.
Where's the sex
This is yaoi not shounen ai
