New to dating

I'm 22 and about 6 months ago, I ended my relationship of 5 years. It was mutual. We're still friends.  But he was my first boyfriend. First love. My first sex. My first everything.

So of course some time has passed and I feel ready to start dating again. The only problem is is that I. Have. No. Idea. What. I'm. Doing. 

I've been on multiple dates already and all except one has been a complete flop. I try to follow the guidelines about what my friends tell me. Be positive. Never bring up bad things. Never bring up exes. Etc. but regardless I feel as though I'm too awkward and after I never hear from them. 

Except one. His name is Kevin. He's a total sweetheart. Smart. Funny. Even Jewish like myself. He is the whole enchilada and our first date was a success (surprisingly). We are even planning a 2nd date for next weekend. At his place, so it'll be pretty intimate and we've already dabbled in the "what if we can't keep our hands off each other" scenario. He thinks I'm cute. I think he's adorable. So far I think this is going really well. We even share the same 5 year plan. (Marriage, moving out of Cali, talk of a family) 

I don't want to think too ahead, but i can definitely see myself becoming exclusive with Kevin sometime in the future. But I'm terrified of messing it up. I'm confident but I'm also clueless as fuck. 

Any tips you can give me? 

Thanks, loves!
