Where do I fall in to things?

Ok, over the last few years I have always just considered myself bisexual, but now I just don't know if that encompasses it. Back in high school I used to go back in forth confused was I gay was I straight. I grew up in a very small community where there was no one to answer my questions, so I never asked them. I later learned a little more and classified my self, but onto what I have trouble with.

It comes down to my attractions and the sex part. I am romantically attracted to both men and women and have dated both. the longest 2 relationships I have had were with women. When it comes to who I am attracted to there seems to be no guide lines. Someone most people would say is good looking doesn't interest me at all most the time. I've never found certain features that stand out to me. I'm kind of like yep she has boobs, so what. Or he has nice eyes whatever. But then i'll come across someone that is like an instant crush and these seem to be the only people I am ever really interested in. I've had sex mainly because that's what people do. I've never not liked it but I really have no desire for it. When I've had sex its like ok that's over what do you want to do next? My brain is always going during sex saying do this or do that I've never been taken away by passion even though I have been in love with the person. Never have I liked porn or strip clubs or had any desire for either.

I guess I might be over analyzing things but it just feels like this is different than the people that surround me. I've always been a conformer. Just lately have I decided to be openly my own person and not hide who I am but part of that is finding out who I am.
