Online dating/exclusivity

Jamie • Married to my best friend ❤️ Stepmama to an awesome 3 year old, Expecting my first bio baby February 2019
I am currently dating a guy I met online on a dating website. It hasn't been going on long, 2 weeks, 4 dates. We talked about it & neither of us are dating anyone else or anything but we haven't had like an official talk of becoming boyfriend/girlfriend or closing our dating profiles. Neither of us are interested in anything casual, so a relationship is where this would be headed. We had sex on our third date (if you have negative comments keep them to yourself because I don't care) What I'm wondering is how long I should wait before having this conversation about closing our profiles? I don't want to rush things but I don't have a lot of experience with this kind of thing. My last relationship was with a guy I started dating in high school, we were together for 3 years. We broke up about a year & a half ago & this is my first relationship since. Any advice or shared experiences are appreciated! I'm 21 & he's 25 so I'm not expecting him to make a big deal of asking me, but I would like to have a conversation to make sure we're both on the same page & I don't know if it's too early or not. Thanks!
