Is it normal that I'm a 19 yr old virgin?

Completely normal. I felt the same insecurity at 19 and it didn't help that my so-called "friends" were really pressuring me to have sex and trying to make me feel bad about it. I'm now 25 and still a virgin by choice (I just never found someone I felt right about having sex with and have since found out that I just don't seem to have a sex drive), and I'm so glad I didn't lose my virginity "just because" (to me, sex is a big deal and I know I would regret having had sex with any of the clowns I was dating and hanging around with at the time).

Virginity is really just a concept, and there's nothing wrong with being a virgin at any age.

Also, there are A LOT more virgins your age than you think. Most either aren't broadcasting it (I always tried to keep it to myself because I felt it was nobody's business, but one friend with similar insecurities who I confided with later spilled the beans to everyone once she lost her virginity and tried to pressure me into it as well) or have lied about it because they feel insecure about it as well.

It really depends on how you view sex, but to me, based off of my peers' experiences, it's best not to rush it and to wait for the right person. Having sex is really not nearly as big of a deal as people make it out to be.
