In certain (but relatively rare) instances, herpes can take a long time to manifest after infection.
If this were herpes, and your first outbreak, you’d likely have flu like symptoms, fever, swollen glands, nausea, generally not feel well. I’ve had two people close to me confide in me when they contracted it, and their experience seemed more focused on the overall feeling of being completely miserable than just seeing something amiss down there. Do you have bumps or blisters or anything like that on your inner labia or in your vagina? I’m just curious, since I’m not sure why you’re jumping to “herpes” when it sounds like your symptoms are mostly on the exterior. Not that it’s impossible, it just seems unlikely.
Sounds like you have an issue with ingrown hairs. Don’t pick at your skin, and you can try applying warm compresses and washing with a gentle soap. Antibacterial ointment can be applied, but I would be careful not to get it inside. I would also probably suggest not shaving again, not like that, anyhow. If you want to groom maybe try a different method, or even just trim the hair with clippers. I have super-duper sensitive skin and I tried shaving bare for years and my skin was never, ever happy about it.
