- can masturbation cause any problems to the penis?
- does it decrease sperm?
Very rarely will the penis be broken. This can happen with vigorous sex in odd positons, but I have never heard of this with masturbation, although theoretically it is possible. In these cases the person has to see a urologist to have it fixed.
Each time there is an ejaculation, or you come, the reservoir of sperm goes down a bit. It is replaced fairly quickly however. Nevertheless it is possible to use the supply entirely. In this case you just wait a few days and it is made up again.
