Getting Horny but Trying to wait till Marriage

I got my very first boy and all of the sudden I've been getting horny when my periods are about to come.This never happened before. I find myself wanting to get eaten out and fingered.I really want him to go down on me and I know he would but I'm waiting till marriage. I think it's probably because he's the first boy to get me wet because we send freaky messages. Is this normal? Any tips on avoiding temptation?
