<human>: Condense the text into a few key points

My ex and I started dating in high school, and our relationship lasted a long three years. We recently broke up due to him moving away, and it took a while to get over him, but I feel like I finally am now.

I am currently in university, and some guys have already asked me out. My biggest concern isn't if I'm ready to see new people- I really believe that I am... But I have no idea how the dating world works, as I had been with the same guy for the past three years, and that's the only relationship I'd ever had.

Are you supposed to only "date" one guy at a time? Does the topic of sex just come up and you share your views on when you should have sex in a relationship? Do you wait for them "to text you first?"

I know that I probably sound clueless, it's just that with my ex, everything just came so naturally.... Maybe I'm over thinking this, but I don't really know what to expect when I enter "the dating world."
