If it didn't need any stitches then it probably doesn't have much to "open it up" in the first place.
I don't think it's gross, looks like a cat scratched you.
I also have this weird thing of comparing fresh injuries to vaginas... I remember when I punched some glass and got an open wound in my hand that needed 7 stitches, for some reason I kept staring at the edges of the opened skin comparing it to vaginal lips.
