plus why are we going to STD/HIV territory now? of curz part of having safe sex is getting test for that, however this is fiction!!! it does not exist in the story unless the author say so.
NOW ON TOP OF MISOGYNY IM ACCUSING YOU OF HOMOPHOBIA!! not every bottom with exp are a carrier of a disease, do not ever spread this harmful opinion of yours.
and no one here will respect your opinion cuz its wrong so BYE, but i acknowledge that your opinion is stupid.

What I don't like about this manga is that the it's not the Alpha's first time to be the uke ( the bottom) he done it MANY times before meeting the seme ( the top)
