RELAX!! seriously, it's all about being intimate, and having fun. as for the love question, I think that, for me, at least, sex is a way of confessing love. can you have sex without love? sure, but I dunno how it would compare.
so, first time. best advice i can give you is to explain MY first time. same age as you, we got the condoms, I had a dorm room to myself at the time, all the time in the world. Tried w/ me on top, and it was tight, and it was uncomfortable and i couldn't get him in me. Felt awful. wanted it SOOo bad, and just couldn't do it. so, we switche up, doggy style, and he told me "tell me if you want me to stop" or something of that sort, and i sucked it up, and bit my lip, 'cuz i KNEW that if I could get through this first time, the next time, and the time after and the one after that would be 100x more awesome. So, I bit my tongue, and he was as gentle as he could be, and it was... not spectacular. it was a month or so before I ... figured out?... how to orgasm, and that really was the icing on the cake. so... I guess hte moral is to be patient. get REALLY worked up before hand, that'll help a lot. wet == good. lube == more good. oral == best!
good luck
