@Admiral_Pectoral: Why do you think this picture (and post #4892304 and post #4796011) qualifies for bed_invitation? The tag has a clear, visually distinctive definition: Someone lifting_covers (arguably a missing tag implication) in a way that seems intended to invite someone else into bed. That is also how it's generally being used in practice. The guy in this picture is just lying there, and while the guy in the other two is clearly beckoning, he's not lifting anything. There are other perfectly good tags that can be applied when someone is behaving in an "inviting" way while on_bed or under_covers (come_hither, presenting, etc.).
