Most men don’t pay much attention to nails. As long as they’re clean, we’re happy. If you want to paint them red, that’s cool - we might even find it sexy. The turn-off is when nails get in the way, when we reach to hold your hand and we get stabbed with a dagger. That said, we like it when you use your nails to scratch our backs. But please, be careful during sex: we want you to be excited, but we don’t want war wounds.
