I suspect the problem may be the frequent masturbation. There's only so many times a man can get hard and reach orgasm in a day, and as he gets older the number of times he can do it becomes fewer, and more recovery time is needed between each. I remember, as a student, I could have sex three times in one evening, don't think I could manage that now in my 30's! Also, if a man is getting hard and coming frequently, each one during the day will be more difficult to achieve.
What do you mean very frequently? I'd have thought once a day was unlikely to cause much of a problem at that age, but more frequently might result in reduced performance.
No idea if the pills have caused a problem. There is no such thing as a pill that will actually work to increase penis size, it's all just con-men preying on men's insecurities. The best thing they can do is nothing at all, but there are no doubt some out there that cause some sort of harm.
P.S. you may get more replies if you use a more descriptive subject title than "none"!
Yea i agree with sammy about the title of this thread and also Frequent masterbation...
A man can only get it up so many times a day lol :P (Of course this changes from man to man)
I would suggest he stops masterbating for a while and just see if anything changes... If it doesnt then maybe a visit to the doctors would be the only answer :)
