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 :)
P.S. you may get more replies if you use a more descriptive subject title than "none"!
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.
