This is keeping me up at night

So i'm dating a guy i've been dating for almost a year now. We dated off and on in high school and now that were matured and reconnected we've been in a pretty good relationship. His family loves me, im not close with my family so theyve really taken me in and made me one of their own.

He's literally such a great guy ,and in theory i should be so happy. I finally got him back. Bur my sexuality is really getting in the way of our relationship. I just truly don't think im sexually attracted to guys. i was traumatized from an early age and i think it may have something to do with it.

I've been questioning if i'm asexual, but i recently realized i'm not because if i were with a woman i know id feel different. I've always considered myself as bi and most people around me know im bi, but i don't honestly think i'm bisexual. I feel somewhat attracted to guys but i lack sexual attraction for them. And this is scary as hell for me. 

Its one thing to come out as bi, but a whole entire new ballpark when you say youre a lesbian. Theres so many cons to coming out :(

my bf might not wanna stay friends

i live with my bf and have no where else to go if he reacts bad

my dad might disown me if i come out

i just dont know what to do :( 

i love my bf but idk if im IN LOVE with my bf
