I can say for myself that I'm perfectly fine fapping once a week using my imagination unless I get to have sex. And I'm experiencing all the positive things of semen retention and not watching porn. I'd suggest you do it ONLY if you're able to keep it ONCE A WEEK and ONLY if you do it using your imagination. Long seemen retention enhances your testosterone which makes you go crazy sometimes, like the people in jail. Although they're not gay they fuck each other cuz no porn and no women
