Any advice for a possibly aual and philophobic teen?

Hello. I'm only 17 (I'll be 18 in May) but as I'm getting older I'm feeling more and more pressures and have to face more and more questions as to what I'm going to do with my life. I do not completely know if I am aual or not but I am in the sense that , regardless of whether it is premarital or not, just seems wrong to me. I know that God created it but I do believe that I will never experience it and I'm happy about that. As for the fear of falling in love (I've never had a boyfriend) I just don't see why I must share my life with someone else (whether it be with a boyfriend or a husband).Which is the same reason why I don't want kids. I think it's not worth the pain and everything and I am too afraid of that happening to me. So I avoid love altogether. Despite my age and how much "time" I have because I'm so young, I am much more mature than people may think. I am always thinking about this and have searched the Internet for solutions but none have given me anything. I want real answers from real people. Serious answers. Help please!! How can I convince people that I am serious.
