Texture of Labia Minora

Hi everyone, looking for a bit of reassurance if possible and hoping you can tell me if this is normal (also sorry for tmi).

So I have quite short labia minora and I notice that when I feel them they feel quite smooth at the top but as I move my fingers down towards the bottom (towards my vagina) they feel quite bumpy, nothing stands out like a zit and you can't see anything really, you can mostly just feel it, the texture is just different (it's like where my labia minora joins the rest of my vulva the skin thickens a little and has more texture). If I rub the minora skin between my fingers at this area it actually feels like there are small stones in there and I was just wondering if this is normal?Does anyone else have this?

I've had two sexual partners in my life, I've had the same one for six years now, plus I have been checked twice for genital warts at the gum clinic (at my own request a month apart as these bumps were really concerning me) plus my partner shows no sign of warts so I am sure that these are not warts.

Also, just to confirm what I am talking about is not fordyce spots (the tiny tiny whitish dots under the skin).

Hoping someone can reassure me and tell me I'm normal )

Thanks for reading!!
