Who should I have sex with?

Ok, so I have three different guys I can sleep with. Guy 1 is a bit older than me and is my instructor in a sport but we’re really close like best friends and tell each other everything and there’s definately a sexual tension between us. Guy 2 is a friend that my friend set me up with who I wouldn’t end up in a relationship with but I could have sex with all I want when I want. And Guy 3 lives in another state that I’ll be moving to but I don’t know if I should wait for him because I know he’ll be the only one I’ll be sleeping with once I move. I’m quite confused. Guy 1 knows I’m a virgin and I’m supposed to tell him when I lose that because we’ve agreed I would. Guy 2 I’ve never met and I’d be having sex with him purely for having sex. Guy 3 asumes I’m not a virgin so by the time I move, I dont want to be so he’lll never know. So who should I sleep with? Guy 1 first so he knows I lost it with him? Guy 2 just so I have some expieriance? Or just wait a few more months for Guy 3?
