For me, it feels urgent, like when i've not eaten the whole day and my blood sugar hits the point where you start shaking. And when i'm in a sexual situation, i feel approved, closeness, intimacy; there's nothing in the world that makes me feel loved and accepted as much as physical contact with someone i allow coming close to me. Hmm, might explain why i absolutely hate touchy people, the ones who touch your shoulder when talking to you are awful.
