Quick question!?

Julie
So, I been talking to this guy for almost 3 months now. We had sex but I wasn't into it before that I thought I had some feelings for him. Could the sex have thrown me off about the feelings or was I just in a vulnerable place? I feel like I'm not ready for another relationship could that also be It? I mean I like his personality and the person he is, but the sex isn't what I expected or could it be maybe I wasn't ready? Does time have anything to do with the sex?
