Am I right to feel superior....?

I didn't lose my virginity till I was 18 and have only ever been with one guy. I tend to look down on other girls who have had multiple ual partners by my age. I see them as unclean and sullied. I'm not religous in any way. There is nothing of more sacred to me than my body and I would feel violated if I slept around, consequently I feel that I'm better than most girls my age. I think a lot of girls are just complete ho's but many are pressured into underage which I think is a travesty.
