Dang, what a great question.
Breast feeding and lactation for sure. I've been trying to induce lactation in myself for a couple of months now. Lazing on the bed, eating snacks, zoning out with the TV on, and pumping has been this totally wonderful ritual that just makes anxiety melt away.
That, generally, is a big thing for me; all the kinds of reductions in stress and anxiety that come from feeding-adjacent areas. Like, sub/Dom stuff; the lack of choice is so remarkably freeing and clarity inducing from time to time.
Things I haven't really tried but want to incorporate include bimboification, which is just the logical extrapolation of the above.
It's great that you enjoy all this. However, unless you're pregnant or were recently pregnant, you can't induce lactation.
Still, I am glad you are having fun.
