Testosterone is a hell of a drug. I’ve known a few guys who have had at least one gf they only stayed with for the sex and were just putting up with her the rest of the time. Those…generally aren’t very good or healthy relationships. Most of them eventually get out of that mindset and (at least try to) find someone they like being with first and also want to fuck besides.

I've been guilty of that and I've definitely felt that "ok, I came, I'd rather be alone now." thing described in the post. Regular sex goes a long way in keeping me interested and the most toxic women I've been with have always been the best at it. There are women in my life who I like spending time with but that kind of kills my desire to have sex with them. It's like subconsciously I'm thinking "why would I want to ruin this by bringing sex into it?" or maybe it feels like I'm degrading them if I think about them sexually or I don't want to take advantage of them. I'm not really sure what's going on with me there. I mostly just don't date these days because I have my single life figured out pretty well and bringing someone else into it is always so disruptive and I really don't get enough out of it to be worth the stress. At least this way I'm not fucking anyone else up with my bullshit.
