I don't think there is because masturbation doesn't make any logical sense, it just goes against our nature and the purpose of our sex organs. And I'm saying this as a huge former masturbation/p*rn addict. p*rn especially is watching other male have sex with the woman you desire while you're masturbating near them (perspective wise). That's like cuckold 101.
I assume prolactin has a role in indicating if you actually had sex. That is, if you peak over x ammount, you did and the body registers it as such. During masturbation, you can't trigger that level even if you try, so you compulsively try and try again.
Yes, this is related to the former point. The body knows what's up even if we think "it's just busting a nut". We have some clue that it's different (how you feel after sex is infinitely better), but we just ignore it. Like we ignore that greasy stinky fast food when we're too lazy/hungry to get a real meal. But we know immediately after it was a bad idea.
There are study references in those cartoons. You can search for it and even get the full text by going to

Well yes, that would be a big indicator, at least it was for me.
That might depend on masturbation habits. I for example got a big shed when I wanked 3+times in a day (which meant about 2h of edging to hundreds of different clips/women). My scalp would get extremely oily and very itchy.
I covered this above. I think real sex is different. But I do think excessive real sex (like compulsive) can act the same way.
I'm 31. I've been masturbating to p*rn since 13. I've had a very serious masturbation habit that was extremely difficult to stop. I'd been trying for 6 years and only recently i've been able to fully control it. I've had other addictions like hardcore gaming addiction, which was
infinitely easier to stop than masturbation. Masturbation for me was by far worse and harder to stop than all of my other vices combined. I managed to abstain 3 months max but even in those times my brain rationalized seeing p*rn to "figure out why I watched". Or watch sexy pics and stay aroused, Or i'd indulge in sexual fantasies which were like mental p*rn. It's a very pervasive addiction. It feels like an arousal addiction more than anything tbh. I'd sexualize (in my brain) any interaction with the opposite sex, even talking online. Only recently i've managed to get a real clean mode.
I'm now aiming for either real sex or no sex thoughts/arousal. I want to be aroused by a real woman that's near me. As nature intended.
