Let's start off with the fact that I doubt that there is any serious problem with your penis. Maybe there was more friction with this masturbatory episode, no harm! Skin turgor can change with the sodium concentration/fluid content. That does not mean that there is a problem. Also, one cannot compare skin characteristics from different parts of your body (if that is what you are doing).

i would like to add that by a "leathery" appearence i was trying to explain that the skin feels thin thin saran wrap and when touched the skin dosent go back to its original shape ..for instane if u pinch someones cheek and let go it goes back to its original shape...when i manipulate an are of skin on my penis it does not go back as if there isnt enough moisture for it to regain its shape.Also the veins appear more visible under the skin
