Redness on the glands of the penis

[Langley24]

Since I was 16 years old (now 23) I have been seeing redness on the glands of my penis. I was a virgin when it all began. The redness is more serve after it's been manipulated through masturbation or sexual intercourse. I have been in and out of doctors and have used endless amounts of creams and nothing seems to have worked. The skin on the top of my glands does not feel smooth. It feels a little cracked and feels a little sore when touched. When pulling back, it's not a smooth transition and looks like the area is very dry and not naturally lubricated. When manipulated for longer periods of time, the redness becomes worse and if manipulated multiple times in 1 day little red dots appear. After a day or so it disappears again and the redness calms but never disappears. Anything such as lube, saliva, condoms, soaps or shower gels will flair the redness back up until such time it is left and will die down again. I am currently using an E45 shower emollient substitute which seems to help the rest of my skin on my body but my glands. I have just been checked for any Sexually transmitted infections and come back all clear. It is very random when the redness appears worse. Some days are worse then others. Please help!
