Should i? Options

[dontwalkaway]

okay i dont really know where to begin,uum theres this guy we had a short thing last year,several months ago,then he changed his mind we we're really good friends before but that happening f**ked things up for ages,i could'nt get over him though,i'm still not,a few months ago we started talking again mainly on msn or seeing eachother out every month or so. I kinda feel we're okay now and can be friends but i want more,but not a relationship. Hes told me alot that he'd just like sex with someone but no relationship. I did always want my first time to be special but now i just feel i want it to be with him,hes had sex before,i've told him how i feel but said i'm not sure. I'll either regret it or regret not doing it. Usually these stupid ideas fade out after a few days with me but this is sticking. So should i sleep with him,knowing their probably wont be any relationship. I want to feel closer to him,but thats obviously not the only reason i would sleep with him,but i'm just basically needing veiws and opinions because i know its probably sounds crazy,but i just need to make a decision.
