about a week ago after i had a shower i noticed that my penis head (gland) had slights cracks in it, i thought this was just because of the soap i had used so i put some aloe vera jelly on it and next day it had gone, i then noticed that the very edge of my penis head (gland) was slightly swollen and purpleish color. my penis head is also slightly swollen and very red when i have an erection. dose anyone know what this is or what may have caused it
thanks
