Strange spot?

I’m caving… I’ve been searching on Google for forever and nothing like this is coming up. I have a few spots just like these (this is one) on my inner thighs right near my vagina. They do not hurt. The texture is no different than my leg. I don’t know how long they’ve been there since I only really noticed them a few months ago (they’re a bit further back there than front inner-thigh 😅). I am not positive for any STIs (though I’m not sure that would even be a suggestion but I’ve been tested recently and all came back negative). They’re just darker tan, perfectly round spots that I would feel a lot better about if I had an idea for what they are. TIA!!! 😅🙃
