My boyfriend isn't much of a hand holder or foot fondler, or anything of that sort. I inquire this: What on earth does it mean when my boyfriend runs his fingertips over the sharp of my nails. I have natural nails. I don't paint them. I don't file them. He loves running his fingers over them even pushing on them backwards and foward while we're watching television. Is it a sign of affection? (I don't want to ask him, because then he'll stop doing it)
