Weird as this may sound, I went a few days off without masturbating. I was using porn too much for my liking, and my fantasies are women centered, but occasionally something will pop in that will distract me. Sometimes it'll be an image of two guys having sex, or me having sex with another guy. That instantly kills it for me and ruins the session. That used to happen to me a lot when I was younger with like old people popping into my head or imagining something religious naked in the middle of my masturbating. Kind of intrusive thoughts, they used to kill the moment and then even if I put them out of my head they would always keep popping up at the worst times.
Well I went a few days without, and today I figured I would revert to the age where I was just discovering all this masturbating and what not, so today when I got off I did it with the mindset of an 11 year old, and it felt so much more fulfilling and healthier. First because I was in the mood for it instead of just feeling like I had to do it because I was bored or something, and if felt like I was reclaiming something that I lost. I do keep having these frequent intrusive thoughts though, and I often times try to entertain them, which kills my fantasies, confuses me, and then leaves me feeling depressed and empty after orgasm. It's fucked.
