What do you do to increase your sexual urge after 40years?
Viagra,healthy food and exercise
I always take the ladies to dinner, they seem to LOVE food, perhaps a buffet I love them, or maybe saturday night at the sizzler, I have sexual urge but I have a hard time using it. If this doesnt work a guy at weight watchers recomended a prostitute.
I've run into this issue lately. My doctor has me on Estratest which is a combo of estrogen and testosterone. Low dose. I've only been on it a couple of weeks so I'm not sure if it's going to work but I'd ask your doc about it. Also exercise improves blood flow to all parts of the body and that has helped me too. Of course I'm female.
