I am suffering with involuntary masturbation without any sexual thoughts during exercise like pushups or pullups without seeing any other person or desire?

I previously told you to eat foods that lower your testosterone levels. Soy products like edamame, tofu soy milk and miso. Now listen to good advice or see a sex therapist.

masturbation is a willful act of sexual self stimulation and what you describe is not that. If the exercises you do cause erections then either change them and do some other kind. Wish you well or stop doing them
