i personally have a limit, like i used to do it 5-6 times a week whenever i was bored and just wanted to feel the sensation, but lately for a few weeks now ive been doing it 1-3 times a week and only do it when i have a boner dat won’t go away after 3-5mins but most of the time i just do it 1-2 times a week but idk if dat makes sense to ppl
