Is it possible to damage your sperm by masterbating frequently, hard or squashed on? what if sometimes your testicles hurt abit, not right after masterbating but awhile after it has a feeling? The reason I'm asking is just that If i have kids I want to make sure they healthy and strong
...no...you wont do anything bad from masturbating
Once again, your body doesn't know the difference between masturbating and having sex. If you were having sex with another person, you wouldn't wonder if you were hurting your sperm. And your testicles would ache just as much.Masturbating will not hurt anything (unless you rub too hard and abrade the skin...use lube to prevent that, if it's a problem). What you feel is perfectly normal.If you want to donate sperm, they have you masturbate and ejaculate into a container, then they analyze it and freeze it. They obvously don't think that masturbation hurts anything. If you defrost it, it's perfectly viable.
