. If I am with a woman I don't know well enough. . I can have a painful hard-on that won't quit and have sex for hours. (No, it is not as fun as it sounds. It's unsatisfying and painful and frustrating) . I can only orgasm and go limp again if I feel emotionally connected to the woman. It doesn't have to be "love", but I do have to know and like her . Being attractive is just not enough. No matter how 'hot' she is. . I can't cum with one-night stands. (Which is why I don't do them) . This is why being faithful to whoever I am with is so appealing. And why I have zero interest in hook-up sites or "professionals". (Don't get me wrong - sex work IS real work! - but such "services" won't work for me.) . Do any other men out there have this issue? .
