I'm 22 and in my first legit relationship and I don't really get the point.
As much as I love my girl, I think dating is basically scouting to find someone you want to marry.
Given my own lack of sexual and relationship experiences, I definitely do not plan to marry anyone at this point.
So I don't see the point of keeping the relationship.
I've been meeting a few other girls and should I try officially dating them as well?
At this point in my life I might as well just stack my experience points
Dating is whatever you make it. You aren't looking for something long term now? Great. You are looking for someone to marry? Great. You just want to sleep with as many people as possible and don't want any strings? Great. You attach your own meaning to it.
Just be honest with who you're dating what your expectations are. You don't have to explicitly state them out of nowhere, but don't lie if they get brought up just so you can get your dick wet.
