Help I’m scared

So I know this may be kind of inappropriate but I just noticed this in my buttcrack😬 I’m not really sure if this is normal but it has me a bit concerned. (Sometimes my but crack splits opens and then there’s a huge cut I know i sounds weird but it’s super painful but

that hasn’t happened to me in a long time though could it be a scar or what))??

(I had to spread my butt apart for these pictures😂😬)
