Is my penis exhausted?
I am 19 years old and I've been masturbating about once a day for three years. For the past few weeks, whenever I masturbate I don't get the same sensation I used to. My penis does not get as hard as it used to and my semen is more watery than thick. Is it possible that I have exhausted my penis?
You may have noticed that some things you used to do that felt good don't feel so good nowadays. That's called "familiarity": once you know how something is likely to feel your attitude towards it and the way it feels will change.
If you want the feelings to return, do something else or stop masturbating for a few months.
Your penis is not a "muscle" and so does not have any inherent strength. Your semen is probably more watery because you ejaculate more frequently.
Just as you cannot wear out your legs, your penis does not have an expiry date. In fact, the more you engage in sexual (alone or with a consenting partner) experiences, the greater the chance that you will enjoy sex throughout your entire life.
