Masturbation is very healthy for both men and women but sometimes you might masturbate too much.
Still masturbation in excess will do no harm to your physical health but too much masturbation might cause a sore penis, or cause you to lose sensitivity of your penis.
The excess masturbation could also cause you to lose interest in sex with a woman and harm relationships but you're not gonna get harmed physically and hurt your health from too much masturbation.
Still it can interfere with your daily life and it's best to slow down on masturbation if you're constantly masturbating throughout the day.
Masturbating is nothing to be ashamed of and in moderation masturbation can benefit your health and even prevent some forms of cancer or other diseases.
You won't go blind from masturbation so masturbate all you want but if it's interfering with your daily life or relationship then working to try and curb the masturbation or slow the masturbation down would be a good idea.
