Flow, a member of Tantus’ new Alumina line, is a double ended aluminum dildo shaped roughly like a bowling pin (though significantly smaller, of course, ranging from .75 to 1.5 inches in diameter and with a length of 9 inches total). For a metal dildo, it’s relatively lightweight, and definitely on the affordable end compared to some of its stainless steel counterparts. It comes in two parts that screw together and can be mixed and matched with other products from the Tantus Alumina line. They are almost seamlessly connected with a rubber ring in the middle to prevent any little bits of skin from getting pinched.

One of the pleasures of an aluminum dildo is that it can be easily heated or cooled for a range of sexual experiences. Getting Flow to the exact temperature I wanted was a bit of an experiment, though I eventually found that letting the end I wanted heated sit in hot water (think: a minute in the microwave) for about 10 seconds heated it to a point that felt great on my clit or in my vagina. One convenient quality I noticed was that when I heated it this way, the side that wasn’t dipped in water was virtually unaffected, making it an excellent handle.

Once I was ready, I slipped Flow in and found that, while on the large end, she slid in nicely due to the smoothness and firmness of her shaft. The pressure I could apply to my vaginal walls with her heavy shaft was satisfying without being overwhelming. Although her shape makes her less than ideal for G-spot stimulation, Flow’s robust design was perfect for firmly stimulating most other parts of my vagina and the easy handle allowed me to manipulate her into the perfect spots. When I came, I found out that my orgasm felt somewhat different, in an exciting and new way, since Flow’s shaft had absolutely no give as my muscles clenched down on it.

Tantus suggested that the Alumina Flow was great for learning to relax my sphincter so I felt obligated to use her anally as well, though that’s not usually my favorite entrance due to the time it takes to relax my muscles. I heated Flow up again and lubed her (any lube will do with an aluminum toy) and my asshole generously. When I started to push her slowly into me, it felt out-of-this-world. The narrow girth was easy to accommodate and the warmth felt wonderful both as the toy entered but also when it was deep inside me. The firmness of the metal made it easy to slide in and the warmth of the metal helped my muscles relax quickly. All in all, a smooth entrance. A word of warning, though—the metal is very firm which could allow you to push it in before your body is ready to accommodate it. Be sure to ease it in slowly so that, though the firmness may make pushing it in easier, it doesn’t lead you to ignore the signals your body may be sending you.

The best part was yet to come, though. I found that once Flow was inside me, I had a series of amazing sensations. First, there was the warmth I felt deep inside me coupled with the warmth of the metal resting between my butt cheeks around my asshole itself. Even more delightful, though, was the moment when I realized Flow angled into the mattress such that (I was on my back) I could rock back and forth on it and fuck myself with flow even as I jerked myself off. Talk about amazing—I had Flow’s firm, warm point pressing into me at whatever pace I wanted and had my hands totally free to do as I pleased. What a ride.

Care for Alumina Flow is easy: You can wash her off with soap and water or stick her in the dishwasher. You can also boil her.
