This is a big subject that's why their is so many comments,!! At 50 was like a stallion i only had to look at a woman and mr cock was like rock, now i'm older sill hard but i sometimes struggle to use a condom!! But you need to find out what's causing your problem and work at repairing it. Firstly watching porn/masturbating can cause a big problem! Over weigh and diabetics is a problem, finding the escort that turns you on is important. I had a threesome a while ago and even though i have a problem with condoms i was rock hard for two hours because the girls where so hot so you really need the right girl in front of you, to keep your mind focus once the mind is focus it sends a massage to the Mr cock..Good luck
