Anyone else feel depressed after fappping?

No, sex with your partner should be different since you are with a real person. It will help you break the fapping pattern.

 

No, those are two different stories; at least for me. My best guess is, that it comes down to how you value these things. See, you probably don't like the idea of fapping too much (your posting on nofap.com might be a hint here) and therefore some kind of depressed feeling kicks in as soon as you do it. Sex with your partner on the other hand has some high intrinsic value, therefore you'll feel good. I guess, it's just an more elaborated part of the brain that does the judgement (shame, satisfaction, pride etc.) here while the craving and addiction part comes from very simple structures that don't care too much about the differences - from their perspective fapping and sex are pretty much the same. However the part that adds value to them and makes you feel good/bad knows the difference very well.

tl,dr: don't worry
