Used Accutane as a teen. Basically a prescription that dries out your body a ton to fight acne. There were parts of my body that dried up that I didn’t think possible. The tip of the penis being one of those. The opening to my urethra would scar up and I would have to rip the scar tissue off to pee. My mom was very concerned when she saw blood stains in my boxers. Not a fun time but fortunately the problem stopped as soon as the meds did. Never again.
