Your lovelife (or lack thereof) is not your friend's business. Your schoolmates are just feeling insecure about their... umm... hormonal urges, and you're not. For some reason, though, they feel the need to make you feel as bad about your urges (or lack thereof) as they do about theirs.
When I was your age, I wasn't really interested in sex or dating either. At least not in me doing it. I was teased mercilessly because of it. People calling me "immature" and such. Not inviting me to parties, etc. (althogh there were other reasons for that) I just focused on doing what I was doing (schoolwork, TV etc) and tried to ignore them, which was rather unsuccessful for the most part. I eventualy got interested in doing those things, but it wasn't really until high school. And I didn't really start dating a "steady" BF until college.
As for what you do with a SO, well, you do the same stuff that you'd do with your best friend. You also sometimes do the "sexual" sort of stuff (kissing, making out, etc) with them that you wouldn't do with someone who was "just a friend"... Since you said you have no interest in doing that stuff, you don't need a SO.
I suspect you may change your mind about that in a few years, but maybe you won't. It's your decision, and you've put thought into it, so go with it. You can always change your mind later, after all...
WARNING: PG-13 language/situations ahead.
You'll date if you want to. If you don't, you won't. Nothing wrong with either way of doing things. If people ask why you won't tell them who you like (if anyone) you can tell them plainly "every time I do, you tease me and that's annoying" since it's true. But that's cliché, after-school special, type advice...
