I'm pretty weird because of this don't you agree?

It's not uncommon to want more than in a relationship, however, it is uncommon to not want at all in a relationship. So yeah, that's pretty weird considering you're an 18 year old guy. But dude, you can't go through life like that - what i mean by that is the only way to get experience is to do it. Constantly avoiding the situation will only prolong your suffering. So i say go for it - after you get over your fear you'll have the time of your life.
