Do people with erectile dysfunction constantly piss the bed?

[Cloaca Rimjob]

I was rocking a massive tent this morning and thought, jesus I'll need to do a handstand in the toilet.
Then it got me thinking. Is morning wood not designed to stop you pissing through the night.

I read that morning wood is your blood just pooling in your dick while the rest of you is in power save mode. Don't know how true that is. I don't think it stops pissing yourself in and of itself, though.
