WithIn the first 5 minutes of the movie there is a full-on sex scene to be witnessed clearly with the woman on top. The woman is wearing a nightie during this sex act.
In the PG-13 version...we see Sharon on the phone while sitting on the same bed that FX is sitting up under the covers in. Both are clothed, but it's obvious they spent the night together.
Dottie admits to Gerry she's having an affair with her lawn-mowing kid and is split up from her husband.
Connie takes a pregnancy test (at this point we don't know it's because of her husband).
Sharon mentions that Dottie had sex with college guys while she and her sisters slept in the same room growing up.
Connie and JJ passionately kiss in one scene and later they talk about it, saying how it's been a while since they had done that (implying sex).
Gerry and Nora passionately kiss and he offers to stick around (implying that he'd sleep with her) but she says "no" and he quickly leaves.
FX tells Sharon that he plans on staying at the house with Abbie and we briefly see her in a bubble bath (no nudity) and he sits on the edge of the bathtub (clothed), implying that they have done or will do stuff together.
Quinn calls Gerry's date with Nora a "little Yuletide booty call;" Gerry and Nora passionately kiss and it's suggested they may have spent Christmas Eve night together.
