Translation of "Crotch" in Japanese

I have an itchy crotch.

局部にかゆみがあります。

Doctor, I've got an itch in my crotch.

先生、アソコがかゆいんです。

"If it's a light workout, OK." "Right, so will we allow crotch-kicking and eyeball crushing?"

「軽くならいいけど」「うむ、では金的と目潰しは有効にするか？」

If you just crouch a little, her crotch can just be seen flicking in and out of sight.

ちょっと屈めば、アソコがチラチラと見え隠れします。

It's geared pretty much towards real fighting isn't it? Apart from the eyes, crotch, and attacks against fallen opponents just about anything goes ...

かなり実戦的ですわよね。目つぶし、金的、それに倒れた者への攻撃以外は、ほとんどＯＫとか・・・。
