First time sex with him. I'm not a virgin.?

There's a special man in my life who I've been friends with for years and we've been getting really close recently... I'm completely and totally falling in love with him and he called me his girlfriend the other day. He knows that I've had years of sexual experience whereas he's never had sex before. We have extremely hot makeout sessions and we've seen eachother topless and come really close to having sex a lot... But... He's really nervous and I wanna make it special for him but I'm nervous too. Taking our relationship to the next level is really daunting for me and I'm worried he'll have expectations which I won't meet and it'll just disappoint him... I dunno... Just really nervous about the whole thing on both our parts.
