Hey,I just recently had unprotected sex with this girl about 1 week ago...and I barely know her... I now have a very small red lump on the side of a dick shaft... Im worried to shit...! There is no pain or discomfort... I cant even feel it at all... Supposedly herpes come in clusters, but so far this has just been one little red lump... Anyone have any ideas at all? Im losing sleep over this completely... Please let me know if you think this is herpes / something else... Hopefully harmless!
