So, I've been in an open relationship with my girlfriend for about a year now. We have an amazing sex life, and (lucky me) she has not had problems with me sleeping with other girls in the past. We have an agreement not to fuck others without a condom, but if it happens, we have to tell the other person and get tested. So far so good. Only, I have had problems in the past with not being able to maintain an erection as soon as the condom comes out. The very act of unwrapping it starts wilting my boner. This has not happened every time I've fucked a girl with a condom. In fact, I've SUCCESSFULLY fucked girls with a condom more often than not, but it has happened two or three times and is completely humiliating. I'm so concerned about the situation that I've invested in generic Viagra. I've taken it, but never under these circumstances. So who knows. It's a maddeningly complicated predicament and I know that it's mostly psychological. I am confident in my abilities, and all my girlfriend has to do is think about my cock for it to spring to attention. But in less comfortable circumstances I may not even get aroused no matter how much I may consciously WANT to. My fears have been renewed because I have a potential new fuck buddy, and I hate/am terrified by knowing I may not be able to control my body. Anyone dealing with a similar issue?
