Pls help

Ok so I have itchiness down there and cottage like discharge but when I went to check I saw pimples idk if it’s from underwear I don’t want to assume herpes bc I’ve been with my husband for 3 years… I have scratched so much I think I cut my skin pls help… I went to doc she did a swab nd she asked if I was scratching a lot and said yes but I didn’t have the pimples at the time…. They Don’t hurt hence why I didn’t know I had them and there is the cut from scratching … it’s like where my underwear goes
