is it right ?

So I'm talking to this guy that I've know almost 6 months.. he's very respectful , funny , positive... we've started texting more and more and his freaky side finally came out, which doesn't bother me but now he wants to have sex and get down...it would be my first....I want to know what it feels like but were young... still in high school..he's a year older than me but  what should I do..?
