Sorry sorry. but seriously... blood is a bit more dynamic than what we would hope.
If you needed more proof then get another lab test but the symptoms speak loud and clear.
There's anylabtestnow.com that, if they're in your area, offers hsv1,2 testing for $40.
Because I think most people lie.
People lie about not having symptoms. People lie that they 'always' use condoms. People lie that they didn't know they had something suspicious.
I think it is hard to catch herpes, but the reason so many people have it is that I truly believe that most people lie about the above things I mentioned. The fact is, no one wants to admit to being irresponsible, so people will say 'there were no obvious symptoms', or 'I always used condoms' or any other BS to deflect responsibility.
Sure, there are a lot of cases where people were genuinely unawares, or who always used condoms etc etc. but I don't think it's as high as we are led to believe on sites such as this.
