Edit: when hard that place I noticed now is a bit endented but it’s not bent to the right at all.
Hmmm... tough question, not sure I’ve heard of anything like this before. It’s possible this is a type of peyronies but since it ends up straight when fully erect I don’t know. I’d say this is probably beyond the ability of anyone here to answer, unless someone reading is a Urologist or happened to have a very similar experience & got diagnosed. Best thing would be to see a Urologist, may seem a little embarrassing but they deal with this kind of thing & stuff that’s even more embarrassing all the time, so I’m sure he/she would not be shocked & most certainly would not judge you. And do answer every question completely honestly - they can’t help you if you hold back what could be a very important piece of the puzzle. For them to properly diagnose you, they need every bit of info you can give them. Good luck, hope you can get to the bottom of it.
