I see, this makes some sense now. Basically, these two are good friends, and don't really have much interest in having sex, because obviously they aren't doing that very much if they just eat lunch together and maybe spend the night together once a week. If that works for them, that's great, but personally I can't imagine having a permanent relationship where we're not sleeping together every night.
