I had unprotected sex with a friend about 1 month ago. 3-4 days ago I began to notice a grouping of bumps/pimples on the head of my penis (only on the head and in no other area). The bumps have not opened up and have not pussed. There is an odd odor as well. Unfortunately, I am out of the country and can't really go to a hospital until I return home as I am on business in a 3rd world country and don't trust any hospitals. In the meantime, I really need to get an understanding of what I have. Some of what I have seems to be related to herpes and some of it doesn't. I've attached a picture (best i could take as a reference).
