Hi  I’m 21 years old openly gay guy and need an advice really bad. In March,my friend introduced me to this straight guy, he became really close to the group (2 guys and 6 girls)  and we started drink all together every weekend after the bar they all come to my apartment to sleep in separate rooms but he always sleep next to me. We started talking every time at night then after a while we started cuddling and ended up kissing. Last month he told me that he had feeling for me and he would like to spend more time with me, I told him that I have feeling for him too but I have a question to him (are you gay or bi) and he said he’s bi. He’s really nice to me and I can tell that he likes me but the problem is every time we all drink together I catch him looking at my best friend (female in a relationship) in a sexual way (we didn’t have sex yet I don’t think he’s ready yet cause I’m his first and everything we do is secret no one knows about it) so I once asked him if he would have sex with her and he said yes, but at the same time it’s weird cause he sleeps next to me and we do stuff. I don’t want to be the guy who’s available when the girl is not available. The other weekend he said that I’m his buddy how can you have feeling for me and still be your buddy so I asked him what do you mean by buddy he said my best friend  The problem is I don’t think he knows when he’s hurting other people and I wanna ask him if he likes me in a relationship way but I don’t want to scare him or ask for too much that I could lose my only guy friend and the other person that I only know about  What should I do
