I think I understand you. Up until this year I think, I liked people of my own age at my own school. But now the only people I like are celebrities, unreachable people. I play a game called Dragon Age and I practically fell in love with one of the characters in the game. I watch a lot of youtube stars too, and recently I just had to pull myself together after feeling like I loved one of them.
Kissing and anything sexual sounds icky to me too! I actually had my first kiss a couple of months ago... at first I was like "Oh kissing isn't so scary!" because I was so nervous then afterwards "Well this is boring." It didn't really do anything for me. Sometimes I wonder if I'm asexual or simply terribly afraid of intimacy.
I always joke that my laptop is my boyfriend, but I'm really only half-joking.
