Thanks for this thread. We have been full swap for a year and I have only cum once with another woman other than my wife. I was thinking I was the only one who had this problem because all of the other guys have cum with my wife. I have gotten to the point that I tell women up front. I have had women thank me for telling them so they would know it wasn't them. I have also had women take it as a personal challenge to be the one that makes me cum. I am hoping that eventually I will learn how to cum with a condom and a new partner.
