My skin is red in areas under my pubic hair- the areas aren't raised and they don't itch or hurt or anything like that. They've been there for a long time- I think the first time I noticed them was 2 years ago. They're not dark red but they're noticeable, and I don't think they've spread at all since I initially noticed them. I've only had sex once and it was about two years ago, but I don't remember if I noticed the spots before or after I had sex. Any ideas what this could be? I haven't noticed any other irregularities.
