My 45 year old boyfriend says he has a lower sex drive than 5 yrs ago. Although he wakes up several time during night with a hard erection he says its not as hard as it used to be and I would say 3 out of 4 times he doesn't cum. He has the sensation of almost cumming but then loses it. He doesnt have any problems during oral sex. At first I thought it was because he used withdrawing and not cumming inside a method of birth control, but I have an iud and so that's not a problem. He takes no medication at all. Is in great shape 6 ft 3" 170 lbs. no extra fat. He does drink occasionally and smoke cigarettes. He does have some back issues from his steel factory job. He says sometimes he has pain down his butt cheek and around to his testicles ( which he swears are smaller then they were). I am worried . This has been going on for more than 4 monthes. Any suggestions?View Thread
