well, I'm pretty sure I have read a couple of other threads really similar to this one before.
a lot of people will say you're a weirdo, but it's something you don't like, people should respect that.
I think that if you keep replaying to yourself how gross sex is, you won't ever enjoy it, and you never know; with the next person it might actually be different.
Why don't you maybe try trying to familiarise yourself with the act of sex, by watching softcore porn, or movies with sex scenes in. then you might be able to see that it can be incredibly romantic, or really sexy... and not something to be ashamed of.
I can completely understand where you are coming from, but it is a natural act. if you love someone, you want to be as close to them as you can, you want to please them you want pleasure back and you find them irrestistable... maybe you just havent found the right guy yet.
I hope you do find him.
