Hi HM2, I'm in my mid-40's and have been married almost 20 years. I'm in good shape(work out 5-6 times a week). However, I'm still 45 and on some blood pressure medicine. I'm not overweight and can see my cock when standing up. Some guys can't. My point is that I too am good for only one go. However, I know this and I give my wife oral for as long as she wants(at least a half hour sometimes 1.5 hours) not consecutively. I also give her full massages and love playing with her ass(rubbing and licking). When I do fuck her, she usually cums again and depending on the position, I last long(behind or her on top). I cum quickly when it is regular missionary. So try different positions. Also, as for him going more than once, do you give him oral after he's cum? DO you give him a handjob? What do you do to get him hard again? If you just lie there and say come on I'm horny, he probably won't be able to get it up. Or you can push his head down and make him go down on you after just fucking you and tell him that when he can get it up he won't have to eat your creampie. If this gets him hard, you might be on to something.
