Here are a few screenshots of the new interactions. The first three show an interaction I added today, while the last is "Beg Pathetically to be Taken Back".
I've been told it's attractive when one's partner fixes things around the house, so I added an interaction where if a Sim has either of the Handiness buffs from upgrading, someone that they've WooHoo'ed with can Compliment their "Handiness". I assume the innuendo won't be lost on anyone.
