best lube

Sliquid Sea.

I love Sliquid Organics (I prefer the regular lubricant, but they make a gel version as well). I am very sensitive, most lubes cause me burning sensations, especially when combined with penetration (which is kind of why I use it in the first place), but this has never caused me any irritation whatsoever. And it feels really natural! I love it, and it has safe ingredients (no glycerin, parabens, etc.)

I really like Wet Naturals water-based lube, never had a problem with it. Even though it is designed for oral, this lube works just great for PIV sex as well. It is claimed to be safe and hypoallergenic.

My boyfriend and I are Maximus loyals. It tastes awful, so it's not really oral friendly, and it's water based, so you'll need to reapply if you're having an extended session, but it's compatible with everything, its great for anal too, and is non irritating. Plus it comes in a pump bottle which I'm pretty sure is the best invention ever.

I'm really sensitive to a lot of chemicals, glycerin, flavors, "warming" "tingling" or cooling lubes.

We use Sliquid Ride H2O. It only has 4 ingredients and we have never had any problems with irritation. It lasts a long time and has no smell, taste or anything. I know it's under "jack off lubes" but we find it the absolutely best all around lubricant.

JO H2O has been our favorite

Pjur Personal glide-Silicone based (for sex and solo)

Maximus-water based (solo, anal, quickies)

Astroglide is good for anal, and that's a sensitive area, so I'm sure it's good for a sensitive vagina too.
