Dry skin problems - please help?

After I ejaculate the skin on my penis head seems to go dry, i dont know if this was caused by me stupidly scratching the area harshly about a year ago. I have small scratch scars from this but if i dont masturbate for a few days then they become less visible, also the scratched area healed but the area considerably more red than other areas of my penis head, yet all of it seems to appear dry after masturbation. I know this is not dried semen or smegma as I shower twice a day and wash after masturbation. Also after masturbation for a few days after I get an erection the skin near my meatus, (pee hole) looks dry and horrible. Help needed please.
