I had protected sex w/ female a week ago & have started to notice a slight itchy feeling on & around anus. Also have odor from genitals. No discharge?

STD and protection. Sean, I assume that the protection was likely a condom. While condoms offer a good deal of protection from most STDs, and they certainly helped prevent pregnancy, they cannot protect you from all secretions and potential viral and bacterial contact. One week is early and typically, it may take two weeks before other symptoms are noted. I would have an evaluation particularly if contact unknown.
