About 3 months ago I met an amazing woman. We started off having protected sex but that changed real quick. Fast Forward to now. I noticed some ulcers and black heads on my penis and my lymph nodes in my groin area are tender. Where I shave my pubic hairs I noticed a lot of scars as well. I went to the doctor and just by looking he says oh no that's herpes. I kind of figured that by looking at pictures online. So my question is, should I trust his medical eye or should I go get a blood test done in a couple weeks. Thanks
