my boy friend has been complaining about a small rash that appears for 1-3 days on his penis after we hav sex. it doesnt happen every time we hav sex so i think it might have something to do with my body chemistry. about 2 years ago i was on the depo shot for 12 months. i stopped treatment bc i was falling into a horrible depression . the birth control i switched to was the 12 year iud .a year after i stopped the depo my hormones went completely out of wack n i couldnt stop menstrual bleeding. i hav now removed the iud and am on the pill to help monitor hormones but i still menstruate twice a month for about 2 to 3 days long. the rash only shows up when its about time for me to start or within the first few days after my period. do u hav any ideas for what this might b???
