I am 20 years old and within the past month or so I have really lost interest in masterbation. I used to do it nearly everday, sometimes a couple times a day...but lately, I'm lucky if I do it once a week. Is this part of puberty or what?
Well, I would be worried unless there is an obvious explanation. Like:
Any recent problems (financial, deaths, threats, job loss, that type of stuff)?
Any recent sexual problems like a sexual encounter gone bad, or thinking you might be gay?
Any recent blows to your body, like a car accident or hit with hard ball?
Any recent aches or pains, like joint pain or groin pain?
Any recent depression, thoughts of suicide that kind of stuff.
If the answer is no, and you are perfectly healthy, then something is not right. Let me know your physical condition, fatigue, weight gain/loss, muscle strength loss, heart beating faster, to name a few.
What do you mean by, "you've just lost interest"? There could be many factors for this. Some people do it alot, and some people don't....If I have alot going on in my life, or stressed, I don't do it much....However, I do love doing it!! eddie
Probably the best thing for you to do is to establish what feels go and then do it. I used to masturbate 2,3 even 4 times a day but have long since settled on once per day, usually around the same time each day. It is normal and it feels great!
It is a normal part of growing up that you will slow down with respect to masturbation. Just do what your body tells you feels good!
