Am I the only one not interested in sex?

Hi.
Something that has been bothering me for the past 2 years is the fact that I'm not interested in sex at all. I'm 17, and never been in a relationship, yet I've had my first kiss and held hands with someone but that doesn't matter. What I'm worried about is my future. Hearing people talking about sex or watching it on tv disgusts me. Whenever my mom and I have these "talks" about sex and protection and how it hurts the first time and other stuff makes me feel weird, as if it was something new when it isn't. As if it only happens to certain people.
I think I'm bisexual because I've had crushes on a couple of girls (I have a crush on one right now) and I think it's the "lesbian" side of me speaking, since obviously lesbians don't want anything to do with men, I feel the same way about sex (Hopefully that comparison gives an idea about how I feel)

I have nothing against kissing or hugging or cuddling or holding hands (even though holding hands in public gave me a lot of anxiety), etc, it's just the thought of sex/sexual intercourse that I'm not interested in. Every day I think about getting married, having a house, and a daughter, but how am I supposed to get pregnant if I'm not interested in sex at all? I've actually googled if it's possible to get pregnant without having intercourse, but none of the answers seem to work, they gross me out.

Is it just some sort of phase I'm going through? Am I too young to think about these things? Because I don't want to get married in a couple of years and not having my honeymoon the way it's "supposed to be". I just think that if it doesn't go away, I'm going to either lose my partner or I'll just have to do it for the sake of wanting a child or to fulfill my partner's desires. Or is it going to change since I'm going to have strong feelings for someone? Am I the only one who thinks this way? In the teen age, that's one of the topics we talk about, and I'm afraid that no one is going to understand that I don't think the way they do.

I think that it's entirely possible that maybe mentally you are just aren't ready fro sex. Many people mature to the topic of sex at different ages. Some start very young others bloom late. I was a later bloomer myself. It also could be just as you said. If you are having interests in woman, it could be the side of your brain that like women that is deterring your thoughts from sex with men. There is no way for any of us to know if this thought process will change for you or not, but given your age, I'm going to guess that as you get older and you meet that guy that is going to change your life and make your dreams come true, your thoughts on intercourse will likely change.
