I think you're visualising the proposal wrong. The duct tape is to provide cushioning. Stick it around the edge so half is stuck on the inside of the bottle and half outside. All the sticky bits are stuck to plastic. No glue is left open to make skin contact.
Trying to think outside the box here, but maybe if she feels the same (and it sounds like you were both pretty mature about all this) you could join the local swinging scene together? Better and easier as a couple than as a single male.
I think only if you have a good reason or don't have 100% verifiable documentation. Before our first child was born the doctor recommended we get MMR again just to be sure. You don't want to risk it around a vulnerable newborn.
You mean brubs and brut?
