We’ve got different needs than heterosexuals when it comes to lube. The cheapest and the most familiar lube is water based lube. It’s cheap, smooth, slick, and easy to apply. It is compatible with all types of condoms, making it ideal for safe anal sex. It’s also really easy to clean up, just a bit of warm water and everything will be good as new, regardless of how much you want to use. YU can buy it with different consistencies, from super thick to thin, and have a million variations, warming, flavored, etc. The cons: Water based lube dries out, and gets sticky and gunky, so you have to slop it on thick, and you have to keep reapplying it.
