I guess this is also a good time for vulnerability since we're talking patriarchy. I've had periods of erectile dysfunction and they almost always overlapped with periods of intense stress or depression. Other times it had to do with my diet. That didn't stop some people at the time bringing up my porn use, which feels really nasty and humiliating when it happens to you.

That isn't to say there aren't men who desensitize themselves, but I suspect that's more prevalent in young men and more of a minority in general. It is a provocative thing to bring up in conversation.
