Hello this is my first time using this site, awhile (maybe a month) back i had intercourse with a girl and now part of my penis itches. Its always the same part and nothing looks different as far as i can tell, also there is no burning or strange smell or anything leaking out. Its not a constant itch and is located on the bottom part of my penis kind of close to the head but not on the head its self. could this be a yeast infection? i noticed her vagina smelled kind of bad. I'm hoping its not an STD as I'v only had intercourse with 2 people in my life. also the itch has only been there a week maybe 2.
