Help answer.

There's this guy that I suspect likes me. He lies on my thigh, touches and holds my hand. Smells my neck, forces me to shower with him and allow him to bathe me, ugh. But the bad thing is, i'm straight. But recently after hanging out with him alot, i realised i've been doing the same thing he does and having alot of fun and gay fantasies, I just needed to get this off my chest, is having gay fantasies (like HARDCORE) normal for me and would you think my buddy is gay? We are both 15.
