So, when they say "penetrative sex" they mean PiV? I would think that pretty much everything else has some degree of penetration involved (or can have it, for instance masturbating a woman or giving her oral sex son't HAVE to involve penetration, but they can.)
It sounds like a weird choice of words to me.
For the rest, the relationship wouldn't work at all for me. And I don't like that they make it sound like people who work differently don't experience "real love".
