I have a somewhat rare birthmark. It's a shaped kinda like a heart/strawberry, but rotated 90 degrees and it's on the right side of my head. My mum has always called it my "strawberry birthmark". You can't see it unless I was to show you, because it's covered by my hair, but no hair grows there, it's just skin coloured but a little pinker and it's a little raised from the rest of the skin.

I also have a small nevus on my left arm near my elbow.
