On my birthday (7/14/17)I went out with an old flame, we got some drinks and then had sex. She performed oral first before we had penetrative sex. 12 days later on the 27th, I get a single swell underneath my jaw that lasted over a day and went away. On the first of August (nearly 3 weeks later) I get a highly mild fever and headache. It goes away by the end of the day after I drank plenty of water. Then I get some weird lesions on the shaft of my penis and I'm wondering if this sounds like an Hsv2 infection?
