I am on the precipice of upgrading my main plate to LTR status (and subsequently attempting the shelve my others, or just letting them drop) and I want to hear some strategies to trigger her pair bonding mechanisms. The Sex God Method has been working great so far. I've also been injecting cuddling after sex and so far I've kept her in "gooey retarded" phase for two months.

What else can I do to trigger that chemical "I love you" feeling from her?
