The S-shape curve and the bulbous head of the Rainbow G are design features created specifically with vaginal G-spot stimulation in mind. Since the Rainbow G is made of a silky tempered glass, you will find that the incredibly smooth finish translates into the need for little to no lubrication. Just a drop of lube on the bulbous head is often all that you will need to pop this baby through your vaginal opening for happy G-spot hunting. Thankfully, you can apply your lube of choice, be it water-based, body-safe oil-based, or silicone since none of these types of lubes will damage this beautiful glass toy.
The Rainbow G also lends itself as an effective Kegel exerciser: the hardness of the material gives excellent feedback when clenching the PC (pubococcygeus) muscles around the shaft. You can also use your PC muscles to push the toy out of the vaginal canal and then manually push it back in to repeat the process. It is fascinating to watch the colorful glass nubs appear and disappear, as well as to feel the undulating curve of the Rainbow G as it is pushed out. This makes for more pleasurable and interesting Kegel sessions, which can often be quite boring. Due to the combined length and rigidity of the Rainbow G preventing full insertion while you go about daily activities, it can only be used for Kegel sessions in a private setting and cannot be discreetly used like most Kegel exercisers can be.

The same features that make the Rainbow G G-spot friendly could also serve to target the prostate, if you exercise caution. For anal play, the base of this dildo would ideally be of a larger diameter to safeguard against losing the toy in the anal canal (though, given its combined length and rigidity, this scenario is somewhat unlikely – yet not impossible). The smaller base would also make the Rainbow G more difficult to use in a harness, though it is advisable to use glass toys by hand anyway in order to more accurately direct gentle movements. If you are interested in using the Rainbow G for anal play, you could always tie a small cord around the base and make a loop to slip around your wrist as a safety measure. I also encourage you to note the dimensions below (under Design / Shape / Size). The diameter of the rigid and non-yielding bulbous head would preclude most anal play beginners from enjoying a pleasant and safe experience.
Glass has the awesome ability to hold desired temperature – both hot and cold – for a considerable length of time, so the Rainbow G is perfect for enjoying an enticing and leisurely thermal play session, either solo or with your partner. When used in partner play, clear communication and gentle movements are imperative, as glass is completely rigid and unforgiving. Bruising tender tissue, such as the cervix, will definitely put a damper on your erotic mood. When glass is wielded gently, however, its slippery heat or coolness feels absolutely divine for teasing the nipples, the clitoris, the labia, and the vaginal or anal opening – and it also provides an exquisite thrill during slow penetration. Please employ care and common sense while engaged in temperature play: the Rainbow G should never be placed in the freezer or microwave, as extreme temperatures can cause frostbite and burns. Placing your glass toy in a basin of ice water or in the refrigerator produces amazing results for cool sensations. For hot sensations, try running hot tap water over your toy. Always test the temperature of the toy on the underside of your wrist before applying it to your more tender and sensitive erogenous zone. In addition to the delicious thermal sensations it provides, glass offers a delightfully non-yielding hardness and a satisfying weight that is noticeable during penetration. (More information on glass is included below, under Material / Texture).
The Rainbow G is very beautiful and whimsically abstract, but it is not exactly discreet in appearance. You could, theoretically, try to pass it off as the blown glass sculpture that your good buddy brought back as a souvenir from Italy, but its undeniably phallic shape triumphantly shouts its glorious purpose to any but the most naive of admiring observers. As long as you have a sock drawer or other private storage area that you can claim as your own, the Rainbow G can easily be stored discreetly inside its storage pouch. For extra discretion, you could always pull a bulky athletic sock over the pouch. As for discreet use, the Rainbow G does not run on batteries or vibrate, so you alone are responsible for any noise resulting from its use. Depending on how you respond while pleasuring yourself, this toy could feasibly be used in a college dorm setting under the covers of your twin-sized bed while your roommate snoozes just a few feet away.
For more privacy in a roommate-type situation, the Rainbow G works amazingly well for use in the shower. I am often frustrated while attempting to use my silicone toys in the shower or bath. The only type of lube that can safely be used with silicone without damaging it is water-based, but I find that both my natural lubrication and water-based lube rinse away almost instantaneously in the shower/bath; this is unfortunate since the texture of silicone produces a frictional drag on skin and some amount of lubrication is usually necessary when playing with silicone toys. So, as a frictionless, slick glass toy, the Rainbow G is ideal for use in the shower and bath. If you find that you need to use lubrication with the slippery glass, you can safely use your favorite silicone lube, which does not readily rinse away with water alone and will not damage your glass toy. For this reason, you can also use the Rainbow G for some kinky and stealthy fun while in a pool or hot tub – though I recommend this only in a private setting unless you have a fantasy about being arrested for lascivious public conduct. Just be careful that you do not drop your toy on a hard concrete or a tile surface. The Rainbow G may be made of an extremely durable glass, but you cannot expect it to be THAT durable!
The Rainbow G would also be a good choice for travel, as long as it is carefully nestled inside its storage pouch between layers of soft clothing toward the center of your suitcase. Since it is an all glass product with absolutely no metal in its design to set off metal detectors, you are not likely to be exposed to embarrassing security inspections at the airport.
