We choose out of the three types of voltages, the JO 9v volt. The JO box is an attractive 6.25" x 3" x 1.5" box within a box. The outside protective box is black in color and somewhat useless, other than the fact it is basically there to provide info of the brand. Inside that box is, in the case of the 9V, a yellow box (Other volts have other colors!). By simply placing your finger on the inner box and pushing removes one box from the other. The yellow box cover lid and back reads "Meet your new best friend". The lid, as my husband calls it, is a coffin lid style box that will reveal 12, single use application golden color plastic tubes of serum. Each tube is about 0.875" small and has 0.17 fl.oz. of gel per tube and are easily pulled out of their packaging holders. These individual tubes are nice when you are traveling, also. Recently, we stayed at a Bed and Breakfast while away for a wedding and there was no need to take the whole box, husband just put two of these tubes in his shirt pocket and we were set. These tubes look as though you can simply twist off the top, but these tubes are pretty durable and can take considerable twisting to get them off, as we found out after the first time we ever used JO. Husband gave up and decided to just bite it off, which left him with a horrible taste in his mouth and numbing. We suggest using a pair of scissors or a nail clipper to cut it off in order to pour the serum out of them. The reason for the mild smell and sharp taste is due to the whos-who of ingredients:
Base:
Oil .Ingredients:Oley Alcohol, Zanthoxylum Bungeanum (Prickly Ash Bark), Olea Europaea (Olive) Fruit Oil, Melia Asadirachta Leaf Extract, Azadirachta Flower Extract,Coccina Indico Leaf Extract, Solanium Melongeno (Eggplant) Fruit Extract, Aloe Barbadensis Flower Extract, Lawsonia Inermis (Henna) Extract, Ocimum Sanctum Leaf Extract, Ocimum Basilicum (Basil) Extract, Curcuma Officinalis Extract, Simmondsia Chenensis (Jojoba) Seed Oil

I'd love to see the garden most of these ingredients came out of....Prickly ash bark? Fruit oil? Eggplant? Basil? I hope it's not the same type of basil I cook with, and I had eggplant! Might have used a cucumber and banana in the past but never thought about eggplant!

Site says Taste / Aroma: UNKNOWN, I think they have that right!

This product contains no parabens and no L-Arginine and is safe and has all natural ingredients.
It's designed to stimulate, arouse, and excite the clitoral region and female genital area and produce pleasurable tingling sensations although, it was a cross for me between tingling, slight stinging, and burning sensation. I recommend using a small drop on the finger but not apply it directly to the clit. I would personally apply it to the clit hood first to see how you will react to this sensation, then use further.
It takes about 2 minutes for results to kick in and this stuff has some power to it that for some, may be uncomfortable. If this tingling and burning sensation is too much for you, this sensation is meant to last for awhile. For me, it was between 45 minutes and 1 hour 15 minutes afterward the fact...but we also used the whole tube. May vary depending on usage.
With us using a whole tube, the serum gradually worked its way internally and had a dual effect. It felt warm and extremely tingly for both me and my husband's penis while in stroking motion. Once sex stopped, the tingling turned to burning and was sort of uncomfortable. You can only rinse up there so much so I had to let the serum wear off. Now, I don't know if that sensation can be reduced after sex if your husband ejaculates up inside you. I would think his sperm, considering how thick and tacky it is, would possibly provide some relief.
Finally, the texture and consistency of the serum is sort of oily to the touch but washes off easily using soap and water. We didn't experience any staining with this product.

We decided to try to get the JO 9 Volt to sample after weighing the option of the JO 12V, I'm glad we got the one we did. For us, the 9 volt was plenty strong. We first used it during our 69 routine and that's when husband discovered a small difficulty. The tubes this gel comes in is very rubbery and doesnot easily remove. You almost need scissors to cut the top off. My husband decided since we were already in position to just bite the top off. That's when the other problem occurred. The mixtures that create this stimulating gel is not pleasant to taste and causes a (as husband put it) numbing on his tongue, lips and any other place the liquid touched. With the gel on my lips and clit, he decided to finger play instead. Now once intercourse started, that was a different story. As my husband lined up his cock with the fluid still on my outer lips, the fluid came in contact with the shaft of husbands cock and eventually worked its way internally. I don't want to say it was a burning sensation but that's what it felt like, but it still felt great. It's sensation was very evident when his cock began moving in and out. Husband felt it also and it was a stimulant for him, also. Added to the heat of the moment for sure. Now once the sex was over, the gel still felt like it was up inside of me and I still felt that burning tingling sensation, and since the action was over, became really noticeable. It took about 2 hours for the burning and tingling sensation to go away on its own. I assume if your husband ejaculates inside of you that the your mans semen would lessen the sensation.
Now, I don't want to scare anyone from purchasing JO 9V because this stuff really worked nice and is WELL worth the price. Trust me, it's not like once it's inside of you that you'll want to run around the house screaming in pain or run to a shower head and get relief...it's a good sensation. For us, once we run out of tubes, we will this product again.
