I can understand the sexual issues leads to divorce. I have a similar issue. Only slightly changed. In my case lack of fullfillment comes from my wife not me. There have been a few times I've even had to fake an orgasm to finish because she was just not into it. I can sympathize with you. From a guys perspective...let me tell you. Bringing up issues with size and performance will only make it worse. Just make suttle hints to it. Find information that is for isses that can be for you both. An example would be like that commercial you see all the time for the all natural male enhancement. There is also a product for women. You can get a trial sample of each for like $6 or something. Get them both and suggest you both take them. Try some roleplaying or something like that. I know it puts the burden back on you, however a guy will not do it. If it is important to you than you must try to do everything you can. I will be happy to discuss it at any length you wish to goto.
