When I Was Born I Had A Birthmark Between My

When I was born I had a birthmark between my labia majora and minora on the left side of my clit. As I grew up I noticed that beside my clit on that side there are no muscles. On the right side I can put my finger there and flex my muscles and feel them, but there is nothing on the left. This has caused my external vaginals organs to pull the the right. Is there a name for this?
