<human>: A couple weeks ago I met a girl that I was instantly attracted to and we seemed to hit it off right away. We started hanging out constantly and talking all the time. Just recently we started getting romantic with each other, one thing led to another, and now we are having sex all the time. I'm talking at least three times a day with a girl that I just met a couple weeks ago and we are spending the night at each others almost every single night. 

Normally, I'd be completely okay with this but the problem is I really really like this girl and I want to pursue a serious relationship. We have an amazing time even when we aren't constantly banging and I just want to make sure I can make our relationship last past the honeymoon phase. Are we making a mistake by constantly having sex within the first month of our relationship? Should I do something to try and slow things down? Any help is appreciated.

Could you distill the essence of the text into 1-3 sentences?
