I sometimes get an erection during the night as is normal I think. In the last year say there has been a light pain (sometimes) on the end within the glans under the foreskin. Pressing it hurts slightly so something is there. Recently I have noticed when I clean under foreskin in the shower there is a patch of slightly redder area on the otherwise clear pink. The area is not raised but smooth just looks like when a capillary is burst under the skin as on the hand. Also I woke the other night to go for a pee no erection and noticed the pain there which funnily lasted only a few seconds (when I pressed it had gone). If I peal back the foreskin the area is slightly more glossy than the rest of the glans. The pain is never present during the day so far or when I pee. Please not this is not on the foreskin but underneath on the soft bit right on the end. It's not balanitis as internet search always gives.
Advice appreciated. Thanks.
