I've just recently begun having some sexual performance problems that are quite alarming to me and has made a bad sexual relationship with my wife even worse. My wife and I were separated about eight months ago for almost three months (we had a number of problems, several of them had to do with our sex life). Not to go into much detail, my wife (she seems to desire sex almost constantly) while separated enjoyed herself sexually with many other men. I admitted to her that I couldn't alone satisfy her sexual needs and in my despiration to stay a couple, I consented to have other men join us. At first I didn't think I could go through with this "arrangement" but the first time we tried it I became so arroused by watching someone else fuck Cas I felt I could handle this "swinging couple's" lifestyle. Cas loved the "arrangement" and became more loving towards me than she had been in a long time. She is quite a dynamic sexual partner and has a great desire for men that are well "hung" (I myself am just over 4" and 3-1/2" in girth). Every guy that has been over has been no smaller than 7", with most around 8" and girth to go with it (one guy was 9-1/2"! I know because she "measures" them). When it's just the two of us I recently have been having trouble orgasming when we make love, most recently I've even become limp inside her pussy and wasn't able to keep an erection. However when other men are with us, my excitement level is such that my 4" dick is rock hard and I cum actually sooner than I ever want and as soon as I see (and HEAR) Cas getting fuck by the big cocks she loves sooo much I'm always hard again. I even enjoy masterbating and thinking about the scenes and sounds that I have been a part of (I think it's the sound of hearing Cas moan and orgasm that turns me on the most), so I know that physically my little dick is "working" ok. I just don't know why now I'm not able to keep an erection when it's just the two of us. Does anyone have any advice they can give, any help would be appreciated because I know Cas isn't going to stick around if I "can't get it up" when she can get more than I have to give her when she wants to.
