how do I tell my guy?

So I've been seeing this guy that I really really like. It's a long distance relationship right now so right now we are on the months between seeing each other. I'm a virgin, I've done pretty much everything except sex, me and my last bf decided to wait. My new Bf is not a virgin, we sext and send pics but how do I tell him that I am still a virgin? With how we've been talking I don't want him to assume I'm like an expert or anything 🙃
