<s>[INST] I've been masturbating since I was 13. Now I'm 21. I used to have much pleasure in masturbating. But Nowadays I don't find the same pleasure I used to have once and also I feel like I'm losing sex appetite along with sex power. Is it a sign of impotence? Am I becoming an impotent? Btw, when I was on my teen age, I masturbated almost everyday then it lessened to 4 days in a week, then 3 days in a week, after then 2 days, NOW its only once in 3 weeks! I'm getting a little bit of worried about my sex life. P.S: I'm still a virgin guy. [/INST] HIThank for asking to HCMI really appreciate your concern, masturbate is physiological phenomenon more precisely it can be a natural instinct, there are many disbelief and misconception regarding this but that is all wrong, masturbate does not cause any health problem, only matter is taking care for trauma either physical or mental, otherwise its okay, hope this information helps you, take care and have a nice day. </s>
