Should you tell the new guy you're dating about the sexual things you've done?

M
I'm not actually dating a new guy, I'm actually 100% single, but I want to know for the future. I've only dated one guy previously and we did everything but have actual intercourse. So I still consider myself a virgin, just a semi experienced one. I'm just wondering if I should tell the next guy I date what I've done. Do I give specifics? Or do I not tell him anything? I'm so clueless! And the fact that I'm 21 and still a virgin is a problem on its own because I'm kind of embarrassed to tell any future guy because I'm scared he'll want someone more experienced.
