My girlfriend and I are ready for , some quick questions.?

In the past both me and my girlfriend have had "just to have it", now we find ourselves in a relationship where we're both starting to care for each other more and more everyday. Hell, i might even say im in love. We have been dating for a month, and we both know that it's a little fast to introduce into a relationship, or at least that's what common sense tells us but there is some serious chemistry here. There is never a spare moment where i don't think of her and it worries me. I've never had to look into the eyes of those i've fooled around with the next day, i've never had to talk to them about it or worry about its impact on our relationship. So i ask you kind people, are we going to be okay? i don't want to get my heartbroken and i know i don't want to break hers, but we are both two very physical people and personally i think wouldn't complicate anything. Please give me your advice, what are some tips to keeping a relationship healthy after your introduce into it, will our relationship take an impact? will it be positive or negative? should we wait longer for ? because i know i don't want to lose her, and i would make any earthly sacrifice for her. We we're both so focused on the physical aspect sex that we never stopped to think about the emotional part of it because we never needed to. I don't want to make it a bigger deal than it needs to be. Please give me your advice, it's greatly appreciated. I'm worried about falling for her and losing her, and why is it that i feel like this when the idea of sex comes into it, more importantly how can i cope with it? thanks again.
