quick facts, I'm 55 yo, married, straight, had very active sex life b/4 getting married and after. the last few months I noticed and my wife did to, that my cum has got a slight yellow color or brown tint to it. should I be concerned??? I'm in good physical shape, not overweight, exercise daily, my unit still works(stands and spits, no viagra). I retired a year ago, quit drinking coffee, and don't smoke cigs as much as I did. I smoke about 3-4 cigs a day. the exception is if I start drinking, i do go out 3 times a week and have few beers and shoot pool. my wife had her plumbing removed a few yrs ago, so her sex drive doesn't match mine, but she accomodates me with nice BJ's and jerking me off. that's how she noticed it. anyone else with similiar experience???? no prostrate problems in my family.
