Sexuality is all about who you find
?sexually ? attractive, not just who you find aesthetically attractive. There is a very big difference. It's also important to remember that sexuality is a spectrum, not "black and white", so to speak. For example, there's asexuality
(no sexual attraction), ?Aromantic
?(No romantic attraction) ?Grey-asexuality (
?very little sexual attraction, but some). ?These can also be prefixed with bi, homo and hetero. i.e. homo-romantic asexuality would be an emotional/romantic attraction to a member of the same sex. Hereo-romantic asexuality (Me!
) is an emotional/romantic attraction to a member of the opposite sex. There's also aromantic asexuality which would be neither sexual or romantic attraction to anyone, regardless of sex. And, if you wanna go really in-depth, there's demisexuality - a sexual attraction to someone after an emotional bond has been formed and pansexuality, a sexual attraction to someone regardless of sex or gender (because these are two different things, of course.)
Okay I definitely went off on an epic tangent then. My bad.
Okay, I'll use myself as an example - I'm asexual, yet I've been in two long term relationships, both with sexual goings-on (for lack of a better term). I only realised I was asexual about 2 years into the second relationship - until then I'd just thought there was something wrong with me. Well, at first I thought the guys were just rubbish in bed, but then I realised it was me who wasn't really enjoying it. Interestingly, it's only the sexual intercourse I don't find fulfilling. Everything else I'm okay with. However, this doesn't necessarily apply to everyone -
I know asexuals who enjoy intercourse too. It's important to remember that asexuals aren't incapable of feeling love, sexual arousal or romantic attraction - they are just not
sexually attracted to anyone, regardless of sex. I
Now, you say you've felt sexual attraction to people in the past? That could simply mean you're grey-asexual - this is a primarily asexual orientation, with the occasional sexual attraction to someone. If you've seen girls as attractive before then so what? I see boys all the time and I look at them and I think "Hey, they're good looking" although it's nearly always in an aesthetic sense, not in an "omg you're so hot I want to bone you" kind of way.
I also want to say here that 17 is definitely not too young to work out your sexuality. People come out the closet at gay/lesbian/bi/trans at that age, why should it be any different for an asexual? I figured out my asexuality when I was 18, only a year older than you (depending on when your birthday is, of course) and I suddenly thought to myself "that explains an awful lot."
I think the important thing to remember when reading through advice is at the end of the day, it's YOU. Nobody else in this world knows
precisely how you feel. They may be able to relate, but that's different. There are some pretty good Tumblr blogs out there, written by asexuals FOR asexuals and people questioning their sexuality. There's also asexuality.org too, which is pretty good for advice, so it may be worth checking them out. I hate to "tell" you outright what you are, but if you're after a starting point, try grey-asexuality
That kind of ended up being a bit rambly, but I hope it helps you on your way to finding yourself a bit. Good luck, and feel free to contact me if you need to
