Okay so I've recently started having casual sex with a man twice my age. I've known him for a while and we've always been great friends. I care about him deeply. He has problems getting hard on occasion and I can tell he is ashamed when it happens. He says he feels like it dissapoints me. Which is the farthest thing from the truth. The last thing I want is for him to feel ashamed. I want it to be as fun for him as it is for me but I feel like that worry that he won't be able to get hard is holding him back from having a good time with me. I don't want this to come between us so how can I make him feel more comfortable when it happens?
