Full thighs, and I've never had a gap, even when I was a child or at my thinnest as an adult. It's genetic (I'm 100% Portuguese.) Plenty of thigh rub in the summer, and I hate wearing the slip shorts so I just use Body Glide.
I don't really believe any significant percentage of the population has a thigh gap, for what it's worth. I reject the whole idea of it being some kind of goal. Some people may be genetically predisposed to it, but most probably aren't. I don't think most significant others care about such things, either. That's just my take.
