Open Question: I’m bi. But my roommates are homophobes. Help.?

I’m 22, and blk with a son. I live with my cousin(19) and bro(21). My bro is a super homophobe and my cousin is a little more tolerant of us. Well all my life I’ve been bi. I was raised by my mother alone so I wasnt the most macho kid. I got picked on all every year of school for being gay. Now that I’m in the real world I find that I don’t want to even talk to ppl for fear they would start to call me gay. I find it so hard to trust ppl because I been alone all my life. I don’t go out or anything just work and home ( I’m like the dad here). When my fam have company over, straight to my room i go. Sometimes I want to come out to my cousin so that I’ll have someone to talk to. But I’m scared he’d tell my bro and they’d disown me. Lol. Ive become more masculine over the years now. To where I would consider myself dl. But the thing is I’m not trying to hide anything its just nobody f#**ing business who I’m f#**ing. Sometimes I like being bi, others times I really wish I was straight. How do I accept myself for me and learn to trust ppl and enjoy life. Also I don’t want peoples perspective to change of me. Sorry so long tried to sum up 22 years of bottled up feelings.
