If you're buying for flavor: start with a flavored lubricant, not a spray. Flavor is what a lube is for. A spray is a smaller bottle doing a narrower job and it will not keep anything wet.
If the gag reflex is the problem: you want a numbing spray, and you want to test it first. One pump, then wait the full time on the label before deciding it did not work. More is not better here.
If you're on the receiving end of a numbing spray: know that it transfers. Whatever numbs a throat will numb whatever that throat touches. Give it time to absorb, and skip it entirely if sensation is the point.
If you're using toys in the same session: stay water based. Silicone lube degrades silicone toys, and nearly everything flavored is water based anyway. Our water based lubricants are safe with every toy material we sell.
If you're sensitive or prone to yeast infections: read for sugar and glycerin. Sweeteners feed yeast. The flavored lubes here use natural or pharmaceutical grade flavoring instead, but if you react to most things, patch test on the inside of your wrist first.
If you're buying it as a gift: a kit reads better than a bottle. The GoodHead kits pair a stroker with a matching glide and arrive looking like a present. A single spray looks like a stocking stuffer, which is also a fine thing to be.
