Doing it for the fun of it and not cause I'm horny 21

Anyone else ever just act sexual online just to get responses and jerk off just to feel something when it doesn't feel that great anymore touching yourself but still look at porn and touch yourself I have ed erectile dysfunction cause of the prolonged Masturbation when younger also struggle with body issues probably cause of it as a adult ATM and kinda sometimes think about acting on hypsexual impulses in public like jerking off in public I find public exposure hot but have no one to do it with and maybe only would wanna to show myself off and get humiliated sometimes I just feel like a cum dumpster even tho I never have had sex I just have been acting out online recently and have been getting explicit DMS on Reddit it turns me on but makes me uncomfortable also
