Please help : Is My Boyfriend a homos.exual? he Always Wants Me To Lick ass hole

Am 26 years old lady and I have been with my lovely boyfriend for 2 years now, and we are so Much in Love….

I am a virgin, but due to his pressure,most of the Times we do oral s.ex… The issue here is that there was a day while we were doing the normal anal, i mistakenly licked his ass hole and he liked it, and now I lick him often… and he has been requesting for it always …..

My question is do straight men get there ass hole licked? Or is he homos.exual?
