Intimacy issues??

So I used to be all about waiting till I found “the one” before having sex then “the one” cheated on me then I found another “the one” then that one was manipulative and gross. So now I’m not a relationship person because I have horrible coping mechanism and would be a terrible person to date but I still like sex. So now I have more or less hook up sex and fuck buddies but no matter how good the sex is I can’t fucking finish and it’s getting on my nerves. I mean it’s getting so bad my sexy dreams are solo and I’ve given up on sex and just doing the job myself. I mean there’s nothing wrong with masturbation but like damn this whole not being able to finish during sex is super sucky. I’m not really sure if there’s a question in here but I just wanted to bitch I guess
