"There can be porneia without skin to skin contact.."
WTF is wrong with these people?
a 2004 Watchtower study says that "Porneia includes such acts as oral sex, anal sex, and masturbating another person—conduct commonly associated with houses of prostitution. "
I suppose you could get creative and avoid skin touching like the plague while doing those, but they make it sound like you could accidentally do porneia w/o skin to skin.
I like how they never fully define the word though, only listing what it "includes" but not what it IS. I guess that way they can add stuff that they don't approve of later.
