Hey,
whenever I masturbate it is always very aggressively is this unhealthy for my penis? I guess you can say my grip is fairly firm, I just go super fast like I find anything slower boring.
It goes the same for sex I find slow and passionate sex boring and I prefer aggressive/rough sex.
Is it bad to put my penis through that sort of stress when masturbating? my penis does usually look pretty red and sore after masturbation.
