Good day, Dear Dr Richards.
Just a few days ago i noticed that erection during mastrurbation was weaker than usual. Not too weak, but now penis is erecting much slower. I haven’t seen morning erection for 4 days.
I’m almost 21 and have been masturbating since 18. Since that time i had several sexual intercourses with women and didn’t experience such problems.
I want to ask does these symptoms mean sexual exhaustion and is it possible to restore my erection without using medicines just by stopping masturbating for a month or more and changing lifestyle?
I live in Russia, so it is too complicated to purchase medicines that you usually advice in similar cases.
I’m looking forward to your answer.
Michael

ANSWER
Michael,
Since there are no other symptoms, I would conclude that you have temporary burned much neurochemicals needed to support sexual functioning. This is quite dangerous and may turn into a chronic case of sexual exhaustion if repeated.
The best way would be to power your activities properly.
Take a break and make some positive lifestyle changes, such as: proper diet, exercise, massages, and positive attitude.
