20 year old virgin with a 36 year old?

I'm 20 years old and still a virgin. I met a 36 year old man who has recently propositioned me for sex. Not out of the blue. This has been building the past few weeks. Should i do it? I want to, but i have a few reservations. I don't care about his life back home. He's going to be here in the area for at least a year so this is something that i could continue, but due to a few circumstances i have to decide within the next week or 2 if this is something i'm going to pursue. And i'm not really looking for a full blown relationship myself. The age difference isn't that big of a deal to me, it's mostly that i'm still a virgin. I obviously don't have much real life experience. And i am self conscious about my body. I've been losing weight recently and i think i look good, but it's different when your clothes come off. I have a belly. Meanwhile, he is literally the most attractive man i've ever seen. If i don't do this, i think i'll regret it. I don't know if he knows how old i am, so next time i see him i might drop that i'm 20 and a virgin. If he is still up for it, should i do it? And do you think he'd care that i'm soft in the middle?
