I have encountered ED-type issues a fair amount in my time (which isn't an issue for me, though it sometimes is for the partner), and I believe the penis is just as in need of emotional safety as the vagina is. I think a ton of men have a hard time in this arena because of insecurity or other emotional issues and I'd be so, so happy to address this and work through it. Though I've found that you just cannot talk about it. It still seems like the biggest taboo and such an insult if you imply that the penis is anything but a machine. It's very frustrating.
