Should I tell him I've never been with a guy?

I've had the idea that I've liked men since I was a young boy, but have never been able to overcome the barrier in my mind. I'm out of a 5 year relationship with my girlfriend, which was extremely toxic to say the least. I met a great guy on tinder and am going to see him this week.My question.. I really want to let him know I've never been with a guy, never even kissed a guy, but I'm afraid this will turn him away? What would you guys suggest? Fwiw, I am 21.
