I think you need to present to a doctor immediately and demand a swab test that includes looking for HSV (preferably using PCR).
What has been your sexual history in the 2 weeks leading into the blisters appearing?
I had unprotected sex with a guy last week, but I am pretty sure he doesn't have the virus as I know that he has never showed symptoms and his previous partner of 3 years tested negative for the herpes virus
is it possible that it could be molloscum contagiosum?
That is one of a number of possibilities, including yeast, scabies, folliculitis etc.
The best indicator would be if there is white pus present in the sores, which is much more in keeping with those conditions mentioned above than herpes.
