Susan Sontag said this quote
“ I have loved people passionately whom I wouldn't have slept with for anything, but I think that's something else. That's friendship -- love, which can be a tremendously passionate emotion, and it can be tender and involve a desire to hug or whatever. But it certainly doesn't mean you want to take off your clothes with that person. But certain friendships can be erotic. Oh, I think friendship is very erotic, but it isn't necessarily sexual. I think all my relationships are erotic: I can't imagine being fond of somebody I don't want to touch or hug, so therefore there's always an erotic aspect to some extent. ”
