My partner and I used this as a mood enhancer and an extended foreplay aid. As noted below, it's quite fun to put on and wear out for a romantic evening, or as part of a sensation-play scenario, given how intense it can be.

The thing is, the way On works is very much subject to the user's body chemistry. Some people will experience pleasant tingling and warming, to varying degrees of intensity. For particularly sensitive people, it might be a good deal too intense. For some, it might even burn unpleasantly. This is definitely a product to test out on less sensitive parts before going all in. Know how it will react with your body and know your sensation limits before applying it to your tender bits.

On is a relatively thin oil which, while I would not recommend its use as a lubricant, provides a bit of extra slip similar to your average scented oil. It's easy to apply and doesn't tend to run much, which is important, given you want it to stay exactly where you put it.

This product has a very strong taste and aroma. On the olfactory front, I consider this a positive; it actually smells like a scented oil I used to use in place of cologne when applied to my skin. It's a bright, spicy scent with lush undertones; very alluring, if you're smelling it on your partner. I'm sure there are play possibilities in that; imagine applying it or watching your partner apply it before going out, and being able to smell it on them, or knowing they can smell it on you. Knowing the effect it has, that could be an exciting bit of extended foreplay during a romantic evening.

The taste is another matter, however. This oil is SPICY. If you're thinking about performing oral sex on a partner wearing this oil, prepare for a mouth full of HOT. If you don't mind spice and a bit of tingling numbness in your tongue and lips, then have at it. But if you like the way your partner tastes without the extra kick, save the oral for another time.

On absorbs into the skin very quickly, and leaves no really noticeable residue to wash off. It's packaged in a little dropper bottle, so it's quite easy to get it where you want it and make sure it stays there.

Overall, I'd say the sensations produced by this product lasted for just shy of two hours, following the slow-building preliminary bit, while the oil's going to work. They were very intense and, for my partner and I, quite pleasant.

The packaging for ON is discreet in that it's small and, if glanced over, might be mistaken for a bottle of cosmetic scented oil or the like. However, pausing to read the (quite clearly printed) label will immediately tell the casual passerby precisely what it is, so you might not wish to leave it lying out.

That said, it doesn't leak, and it is small. Therefore, it's quite travel friendly. Pop it in a baggy with your toiletries and go!

On creates a tingling, warming sensation which is quite intense. As noted above, it's a love it or hate it product; either it works with your chemistry and sensitivity-level and feels good, or it doesn't.
