so conflicted and confused

so I know I'm not straight. I've known for a very long time.

I'm currently dating a man. he's brilliant, kind, works hard, funny and good looking.

I've been through hell in past relationships. I've been sexually abused by two different guys. one of those I nearly married. I gave him everything. I loved him more than anything. I'm still not over what he did to me. so this may be a trauma related thing.

so this guy I'm dating now. he's like perfect for me.

I like girls too. a lot.

here lies the problem...I feel nothing. I feel no desire, nearly the opposite some days, to have sex. I feel nothing romantic. now, we've only been seeing each other for about six months.

anyone have thoughts and/or advice on this? I need opinions. I don't know if this is trauma related or sexuality related or both. i am terrified to hurt him and I also don't want to drag him along. but I don't wanna miss my opportunity with such a great guy.
