Thats an interesting technique. Don't think I've ever seen it before. Usually a ball of the foot roundhouse kick or thrust kick would be used. I guess it woulds work. Its probably a thai style kick. Also, the instep wouldn't be used. Striking points of the foot are ball of the foot, heel, lower...
Mana's past actually makes sense. It's not always the big traumas that get you it can be those micro traumas that do you in. I know because i have gone through something similar and it still messes me up with my emotions.
I like boobs too, but legs are where its at. Strong and beautiful legs from the hips to the toes. So beautiful I want to be kicked by them or choked. You understand if you are like me.
