Hi I have had an itching scrotum and penis lately I have no bite on my penis head itself just on the foreskin. I did graze my shaft whilst masturbating and I don't know it has healed properly but there also red lumps on my scrotum they aren't pimples or blisters they cant be popped but they get really itchy as does my shaft. I also have a few blisters on my hand witch I think may be scabies but the signs around my genitals may that be scabies as well.? Any and all help would be much aprreciated
