There is no normal frequency for masturbation. Some people do it every day (or several times a day), some a few times a week, a few times a month, etc. Everybody is different. You might want to try masturbating less often to increase the quantity of your semen.
Thanks..so is there a way to improve the semen quantity. And i masturbate mostly by watching porn. Is this ok. Is there any sex tools to help in masturbation.
You are masturbating? Why then are you worried about sperm quality? Are you a donor of some sort?
