Your article on older male. Iam a senior citizen. I have no idea how often older menr ejaculate.I would like to do it often but how often, I have no refernce material.I read that if I ejaculate often it reduces the posibility of prostate cancer. How often is appropriate? I note less volume with age. If I take a 1/2 of viagra it increases the event. Any advise will be appreciared. Thanks, ready to go.
