Question about Erection Duration

[55chevy]

I'm not really sure if this is the place for this thread or not. If it isn't I'm sorry and please move it to wherever it needs to go. Now for my problem if you can call it a problem. I'm 38 years old, as I've gotten older I have found that the time length of sexual encounters can last longer and longer. I have never had a problem getting it up but I feel the quality of my erection suffers as the session grows longer. I'm not trying to be funny or anything but after forty minutes or so sometimes I find myself wishing it would get a little harder again. Is there any way other than meds to help the duration of an erection. I've thought about a cock ring but haven't ever used one. It's kinda a catch 22 proposition. When I was 18 I could hammer nails with it but couldn't last that long. Now I can last longer than my erection can. I exersize three to five times a week and I'm in pretty good shape. I try to eat right and take care of myself and I do a kegel routine several times a week. Anybody got any ideas how a guy can stay harder longer.

try l-arginine, that stuff seems to work great for my erections and even sperm count as another benefit, great product
