I'm depressed with my symptoms

I’m been getting red patch on labia, sometimes pimple and itching .i have checked HSV 1& 2 .bt result came as negative .I didn’t have sexual contacts.consulted doctor ,doctor told I got it using public toilets.can I know herpes can come without having any sexual contacts like public toilets and low immune system?
