I am entering my mid-forties and finding that my ability to come multiple times is diminishing. In my twenties I could have sex and come at least three or four times in a day (though that was certainly not an every day experience), twice would be no issue. Now, I may be able to come twice in a day, but would then be "dry" for at least two or three days. Also, I have never had a large volume of come, seems to be less than normal - well at least if I go by what I see in porno movies.

Anyone have any good suggestions on how to increase my body's production of cum/ ejaculate/semen?? Taking zinc seems to help a bit I have noticed but only a bit.
