What is it about girls?

Hey,

Growing up I've always been interested in girls sexually from an early age, very early, I've never really been interested in guys sexually, I've found them attractive and I've been in relationships, but a guy has never really turned me on where as my boyfriend now who I dearly love he gets me like no guys has ever gotten me, I know I'm bisexual or bi-curious, he knows and he wants to make sure I'm happy in anyway, he encourages me to think about girls during sex because he knows it gets me a lot, he's okay with all and is even willing to let be experiment with girls but I couldn't do that to him.

I've struggled to accept my sexuality growing up confused a lot, and most of the time I was convinced I was lesbian although I've never tried it but the amount of girls getting me it's got to be something there. I wouldn't say I have a type, it varies and within this relationship it seemed to die down but since the past couple of months it's come back up and I can't ignore it where he's obviously encouraging me to explore so I can get happy, with that I've noticed that a lot of the girls I find attractive are the ones that throughout this relationship has made me insecure I guess in some way that might be because I was actually attracted and worried that he was. He doesn't seem interested in anything else but after long conversations he would have admitted to having sexual or normal feelings or anything like that but he hasn't.

I know there is several aspect that may contribute to my sexual feelings, but I don't understand what it is about a woman that makes me so "frustrated", I want to know what it is, I often find myself looking at girls and I just general don't know what it is about that gets me, I was wondering that any one else within a similar situation would be able to help me understand what draws me to getting turned on by women so much?

Any answers, suggestions or anything would really help?

Thank you so much
