Boobs and sex

So I weaned from breastfeeding about a month ago and if I squeeze my boobs I can get a couple tiny drops.

Anyway, during sex my spouse and I like boob play. Where he squeezes them bites and sucks on them. My concern is if he’s getting any of those drops that come out? And if he’s squeezing them and sucking on them will that signal my boobs to start production again?

I don’t want to start producing milk again and I don’t want to chance mastitis.

Should he leave them alone until no drops come out anymore?
