Masterbating out of shame
I was shame-jerking in gym showers trying to clear my mind of what happened last night
1. Masturbating with tranquillity until you finish, then you feel immediate shame for jerking off/ jerking in (if female)
2. Jerking off the something that gives you shame (Hentai, loli porn, BDSM)
Man 1: Hey dude, I think I had a Shame Jerk yesterday. Everything was going good until I finished and then I realized jerking off to loli porn is not ok!
Man 2: same thing happens to me when I bust, except I always feel shame for doing such a disgraceful act while looking at a picture of my sister
