What is wrong with my penis?
Well I take cold baths (the tub is filled with cold water) because both of my feet are sort of injured so I can't exercise in any other way. I decided to "push myself" and made the water very very cold (VERY COLD). I stayed in there for around 20 minutes (I'm sorta used to it).

Well today (4 days after the shower) I noticed that my penis won't get fully erect o_O. It is somewhat softer than what it usually is when it's fully erect. I don't have pain anywhere on my penis, it just feels like there is decreased blood flow whenever I have an erection.
I won't be taking any more cold baths btw....

My penis also does not get as full as it usually gets when it is erect. I've had this problem yesterday and today
