This thread is why this site, and sometimes MF, are invaluable. Spark asks a legit question about a specific kink. (This isn't my fetish, because when you may need smelling salts and a first aid kit, I'm out.) But I think knkyngslave and DommeLynx gave practical and sane advice. Kudos to Spark to ask the question, and knkynslave and DommeLynx for what looks to be great advice.
