Most Helpful Guy
I know you don't want the whole under 18 thing but dating and how guys and girls see it radically changes from when you were 14. I know it can seem awful if you've never actually been with someone that made you happy and feel good about yourself but that doesn't mean they aren't out there. Part of finding someone to love is the willingness to endure a bunch of bullshit on the way to finding them. If you don't want to date for right now that's fine. There's nothing wrong with that but if it's because of fear of someone not loving you for who you truly are as a person don't let that fear control you. You really aren't alone in having a tough time finding someone special.

I know you don't want the under 18 speech, but seriously you have all the time in the world.
People's wants radically change between high school and college ages.
The growing up period changes a LOT about a person. It's when you form your long-term goals (and don't change them - for the most part) and know what you are really looking for in life.
You really are too young to know exactly what you want.
There will be plenty of guys (when you're older) who will like you based on your interests alone! High school boys/girls are too fickle. Y'all are still developing. Seriously, give it time before you decide to throw aside guys for the rest of your life :P
But you know what, even if you do want to be alone forever, there are people that are happy with that life. They basically substitute a boyfriend/partner with family and friends. I could never live that life, it'd be far too lonely, but I know there are a lot of people that preach by it.
