My balls are really droopy all the time. and my orgasm seems to be loosing its sensation.

Here are some ...: The size (length) of the sac widely varies among men and has nothing to do with orgasm. Remember: Your testes are inside the sac which has well protected them. As to the intensity of orgasm, it may widely vary from time to time among men. Generally speaking, the older, the less and the more often in sex and masturbation, the less. So, try not doing it more than 2-3 times weekly if possible.
