aging and ejaculation

I'm experiencing a dramatic slowing of the flow of semen during orgasm over the last year. The quantity is reduced, although I seldom go a day without having an orgasm, and the waves that accompany orgasm are slower and there are fewer of them. The sensations are still very good, although they seem to be weaker than in years past. <br> I have had chronic prostatitis over the last 2 decades, although I've been feeling fine lately.<br> Can anybody chime in on this or offer any medical advice?<br> I would like to address the issue if you can and restore some measure of my former experience if possible.

I am 47 years old.

I am almost 48 and I have noticed the same thing--less volume and intensity than before..also some testicle shrinkage in the last two years or so. I think this is a normal consequence of aging. Have you tried Arginine? Some people say that helps.
