Should I or Should I not?

I'm a virgin. It's by choice because i feel i'm too young for sex. The guy i've been hanging out with lately is not a virgin. I know he would never pressure me to do anything i don't want to do, but what if i feel pressure on myself. I have anxiety and make everything into a big deal.  I know i'm not ready for sex, but it's almost like i'm trying to convince myself I am.
