I'm a trans masculine person with a vagina and I'm on testosterone, meaning I'm very dry and can be hurt easily. I've been using this lube for over a year now, and it's wonderful. It feels thick like silicone lubes, but is toy safe and washes off completely because it's water based. I use it alone and with partners, and have found that I don't need as much at a time and don't need to reapply as often as with other water based lubes. It feels more protective against tearing, but not so thick as to get in the way of fun. I've had other lubes irritate my urethra before, but this doesn't, which is lovely.

I've used H2O JO with other body parts, silicone dildos, a silicone coated vibrator, a twisty glass dildo, a "velvet" coated slimline vibe, and a hitachi. It's worked really well for all of these in terms of keeping me slippery. However, it has a tendency to travel up my back when I'm laying down, face up. Definitely put a sheet or towel down if you're on a surface you don't want to clean later. It leaves a mark on cotton sheets even after it dries, however a trip through the washer takes care of that nicely. I suspect it would leave stains on other plant fibre cloth such as t-shirts or hemp rope, so be careful.

This lube isn't good for hot temperature play or oral sex. It takes a long long while to warm up to a comfortable temperature once on genitals. This is a negative for me, but could easily be a plus for someone else. Holding the lube in your hands before applying it can help warm it up. As for oral sex, it tastes absolutely god awful. So much so that I schedule receiving oral before I receive anything else, because otherwise I'd need to wash off.
