First, I hope the ex thing is just you fantasizing. Not the scenario (duh lol). I assume it's just a fun kinky way to help you get over the breakup, I guess. I had an ex (well, it's complicated) that ended with us basically ceasing communication due to them not being honest with me. They basically ghosted me for a year after I got kicked out of a Discord group with poor excuses. At this point, I don't have any legitimate issues with them; I hope the ex and their new significant other have a good time.

Geeze, I'm sorry you had to deal with that. I definitely know what you're talking about. While not as bad, I did fap 3 to 5 times a day when I was generating more of this stuff in the summer. IDK if I got a sore from rubbing w/o lube; if so I probably stopped before I got burns lol.
Yeah, I've had my own fun generating images and rubbing one out. Some of the stuff you can generate is honestly pretty impressive and kinky! At the same time, it's REALLY tempting to just keep fapping if you get yourself into that horny loop. Its important to stop yourself when it happens.
For me, I'll usually just clean up and do other stuff like play games or watch old G4TV shows. That way, I'm not just immediately trying to fap again. After 10+ minutes, I might be tempted to fap again if I get horny. If this happens, I try to pause and consider if I wanna do something else. For me, I might go "maybe I should try drawing" as a way to channel that energy. Though I TRY not to touch myself when I do since I end up getting too horny. I end up feeling too impatient and I mess up on the drawing or I ejaculate and then I immediately loose interest.
I guess it brings me to my last point: do you have another way art medium you could make such stuff (including writing stories and poetry)?
>tl;dr Yeah, like regular porn addiction, it's important to be aware when you're getting sucked into it. It helps to have other hobbies you can engage in. Even better, maybe making your own art.
