Try sesami oil to massage. It is good for the skin.
Hi Concerned, OK, look as we get older the skin on our p***s's gets darker, its the same as hairs will start growing out of your ears, like a forest, its just down to ageing, when your put moisturizing on your penis, and it goes the way you wont it to look the goes off, well try a little extra next time and start doing 3 times a day, and when you get out of the bath, its because its soaked up water, and as it drys its just goes back to the way it was, thats just life.
The next thing is to see if you can start cutting back on your meds, if you think your over your depression, just kick them into touch, and get back to the real world, masturbating is ok if you try and keep it speacial say just a couple of times a week.
Look you can only see how you go.
Good Luck
