water-based, oil-based, and silicone-based lube are all suitable for either vaginal or anal sex. many people prefer silicone-based lubricants for anal sex because it’s so long-lasting and durable, which is helpful when you’re working with an orifice that won’t naturally lubricate itself. oil-based lubricants are also a no-go with latex condoms, which is relevant for both vaginal and anal sex. beyond that it’s all a matter of personal preference!
thank you dildo-smith Matt for chiming in, and while we’re at it let’s actually just go through the whole tl;dr pros/cons of the different families of lube!
water-based:
pros: easy to wash off/clean up, safe for use with any toy material.
cons: dries up quick and needs to be replenished often during sex.
silicone-based:
pros: long last. extremely long lasting.
cons: can be a pain in the ass to clean up, and not good for silicone toys as noted above.
oil-based:
pros: long-lasting, and often the best choice for folks with allergies/sensitive skin triggered by other lubricants.
I really appreciate when people share info even when it’s not relevant to them personally! you never know who might be following you who will really benefit from seeing it :)
