I've know this guy and his family for a while but things recently turned more romantic. We recently slept together (it just kind of Happened) and now I'm worried that it was too much too fast. Or that he will lose interest. We still text and chat almost everyday. And we have hung out several times without hooking up. But I just wanted to see what other people thought?
Some relationships I've had have lasted months or years and we slept on the first date. Some I didn't sleep with them for weeks or months and they didn't last. So it's not necessarily an indication of whether it'll ruin anything.
It lessens the chance of a real one developing since he already sampled the goods, especially before creating an emotional attachment to you. In this day and age, if you don't have a serious talk about where you stand in your relationship, then you're not in one. You'll just be FWBs.
