I am a male age 27. 5 weeks ago I had condom-protected intercourse with a female stranger. 2 or 3 days later I noticed a tingling in my groin, legs and buttocks. I then developed three small blisters (two on one side of my thigh, and one on the other) - with a yellow top and clear fluid when they burst. My general practitioner doctor in Australia  was not sure if it was herpes, and swabbed the top of these blisters. The PCR HSV1 and 2 tests were negative. The Dr did two successive further swabs on the site/dried blisters - again PCR  HSV 1 and 2 results were negative.  A few more sores appeared at the same site then disappeared within days - I did not get these swabbed. Following this (about 3 weeks after the date of possible infection), I had an iGG blood test – this was negative for HSV1, 2. The Dr advised me that based on the tests it was unlikely I had herpes (despite tingling, sores etc). About 2 weeks ago, further small sores (spaced quite a distance apart) appeared on my buttocks and upper thighs, accompanied by tingling in my legs and buttocks. A different Dr opened one of the blisters on my backside and swabbed it. Again, PCR test HSV 1, 2 was negative. I have continued to have neurological tingling in my groin and buttocks and upper thighs. And just yesterday (5 weeks after possible initial infection), another small sore has appeared at the exact site of the initial sores at the top of my thighs. I am very scared. My girlfriend and I had intercourse once a couple of days ago (when there were no sores present) but not any other time.   My questions A) is it possible to have herpes symptoms like I have, but repeated negative PCR DNA tests? B) if I take an anti-viral medication, will it affect the accuracy of a future iGG blood test? (I know that the blood tests will be more accurate if done 3 to 6 months after the date of possible infection). C) Is there a risk of infection to my partner just by cuddling in bed (both wearing underpants)?
