So backstory,
I have had this friend, let's call him F, since highschool. I met F when I moved with my family and started doing cheerleading at a local gym. 
F has always been adamantly "not gay" I think because he did cheerleading as a guy he got really insecure about that aspect of himself. However due to that he sometimes seems a bit homophobic.

Then there is me, I'm transgender, I started transitioning when I was 14, before we moved and while I haven't had any surgeries, I look like any other girl and can tuck preeeety well, so it was just something I never bring up to anyone. Only people who currently knows I'm trans, besides my boyfriend, is my family. 

So today, F, my boyfriend, and I are all going to see a movie at the mall. I really like dresses and I have this particular one my bf likes, so I wear it a lot. But this dress is short. Like if there is a breeze you can probably see my underwear. But due to tucking, it doesn't really bother me when it happens.

So we get our tickets, and start going up the stairs to our theater. I lead the way followed by my bf and F. F made some comment to my bf I didn't hear. I didn't think anything of it.

During the movie my bf texts me and asks me not to hang out with F by ourselves any more because apparently the comment F had made was about my butt and how much he liked it. Apparently he was looking when I was walking up the stairs in front of them.

I tell my bf not to worry, F wouldn't be into me like that, due to how adamantly "not gay" he is. But my bf says that doesn't matter because F doesn't know i used to be a boy. But my bf has never seen how F gets when someone questions his sexuality.

So after the movie I make a joke about F liking dudes asses, which I find hilarious(trans haha so funny) and F goes into his "I only like girls, that's why I even did cheerleading in highschool just to be around half naked girls... You're just being judgy because cheerleading.." blah blah. So I think it's good of a time as any, and so I tell him he's actually gay because he admitted to liking my butt and I'm actually a dude! 

Well, that didn't go over so well. He thought I was joking so I explained that I'm trans. He wasn't mad or anything but just got really quiet. He said he didn't care if I was trans but that he's not gay and I should have told him earlier so he wouldn't have said "gay shit" and that it's rude for me to call him gay even though I know he's straight.

I felt kinda bad because he stayed quiet the rest of the night like he wasn't having a good time.

So Reddit, AITA for calling my friend gay?
