need help

Hi Doc I am curious about a blister that i have on the my foreskin I am uncircumcised. I would have to say that it is not a STD i have not been sexually active in the past six months. I have only been with my girlfriend and we practice safe sex. The blisters were two very unnoticeable blisters that itched one time. I scratched the blisters and clear liquid came out,  the blisters have not multiplied and the area does not itch. But two tiny open lesion remain the only thing that I can think of is stress or masturbation. I've never had any STDs in the past nor have I had any unprotected sex. I would like to know what could cause this?

Blisters on the genital area are not normal so anytime you have one - it's well worth follow up with your provider.  Condoms do not prevent herpes 100%. Have you and your gf ever been tested for herpes to know your status? Since it's been 6 months since you last had sex you can go get a type specific herpes igg blood test now since your blisters have popped and are not longer able to be cultured.  Get a full exam at the same time to start trying to figure out what your symptoms are from if the herpes test comes back negative.
