Man this sounds real, so I shouldn’t compare it with a manga plot. Maybe he was curious and if he was okay with his best friend on top of him, ig he got over his homophobic self? You should tell him to talk to you and make sure he knows your okay with it. oh yeah no misunderstandings! They are the worst

first of all, he seems to be a huge case of closeted guy thing, so even if you pop in it wouldnt help that much, but maybe tell him that its ok to like guys and that you're always here if he needs to talk to someone. also rememebr to tell him that you wont out him, cause that would be pretty shitty of you. just wait, they will figure it out on their own, but its not your fault, so relax

Yeah this definately sounds like internalized homophobia. My sibling had the same thing happen. (well almost) Don't worry about it and sit them down if you can. Maybe just talk with your cousin first. Try to make it sound like he is normal and there is nothing wrong with it and make sure he knows that he can count on you for advice or if he just wants to vent.

About what happened at his house, i dont think thats really important, whether he's in the closet, experimenting, or just playing around, personally i dont think you need to focus on it that much. If you think homophobia is wrong just make that clear to him, and that you dont agree with him on that aspect. If he is a closeted gay, he can find it supportive, and if he is really homophobic then you have simply made your stanse clear on the subject.
Hi uh...this is the first time ive talked bout this cause i think its rlly personal.I have a cousin (boy) he's homophobic asf,he always make rude comments whenever he see gay couples/people.everytime i ask him why he hates gay people and his answer are always "i think being gay is dumb,,who in the right mind would date the same gender as their's" well...i let him be homophobic idrc but the only thing i hate is his guy bestfriend who's also homophobic,they would go around facebook and would stalk gay pages and leave hate comments using their fake accounts.I tried to introduced him to Bl cause i just also knew bout it like a year ago (btw this happen like 5 months ago so this is still kinda embarrassing to talk about) i showed him bj alex which is my fav yaoi back then. He was terrified and flustered at the same time Lmfao it was so fun seeing his face turn red because of anger.Days past by i would always tease him of reading Bl and of course he would get mad.One day he ask me where i read those yaoi free...i thought he was interested in reading Bl and tease him he got mad and told me he only wanna read manga since he's "been to anime lately" (wait omfg this is too embarrassing to talk bout:DDsorry)
so days and days and days went by i always see him with his guy bestfriend hanging around and thought it was rlly cute.I went over to his house because i think...they had a huge taco party....I didnt see him there and thought i was weird i went upstairs where his room is and i open the door (which is not lock btw) i peeked and saw his guy besfriend being top of him and grooping his fucking chest Usjavau it was so fuckingd dumb of me to not knock before coming in he saw me and immedietly jump so fast that his besfriemd flew over to his pc set upI was shock and ran away back home.I dont know what to fucking do,i want to explain to him that i wont mind him being gay,but idk how to make it up to him.We have the same school and i hardly see him with his bestfriend.and oh i havent talk to him since then.help
