<human>: Give me the gist of the text in a nutshell

I just turned 22. So I'm having a past year retrospective. 

While I was 21, I've been in relationships with 4 girls that I've ended. In between, I went on more dates with others. Overall it's fun. Having someone who cares about you, wants you is a good feeling. Having sex constantly is great. 

But beyond that I just haven't felt much for any of the girls aside from physical attraction and slight fondness. It starts off fun, but when they get deeper into the relationship, I sometimes feel like a scumbag for not reciprocating their feelings for me. For example, one of my ex-gfs told me she loved me because she and I are so similar. I absolutely feel nothing of that sorts, in fact I don't see an emotional connection at all. 

I'm not a sociopath, I have many friends guys and girls that I care for. I just haven't felt that way for a gf yet. The reason I date so often is because I am trying to find the one yet this is causing a trail of shitty relationships and disappointed girls. I don't actually feel that guilty as no one's really in control of how they feel.
<bot>: I date girls often, but never felt particularly close to any. Relationships feel hollow/shallow to the point I feel like it's only physical.
