Welcome to the pleasure of strapless dildos! Like the name implies, "strapless dildos" are dildos that aren't compatible with or don't require a strap on harness. In most cases, this means that they don't have a flared base. A strapless dildo is commonly made from firmer materials like stainless steel and glass to make both ends functional - though some strapless dildos are crafted from a rigid silicone as well.
As a strapless dildo, by definition, doesn't have a flared base suitable for the "regular" strap on harness use, they lend themselves well to a design of a double ended dildo - and that's something a lot of manufacturers take advantage of. Many manufacturers provide different shapes or textures on either end, so you really do get two different dildos in one!
Is this your first strapless dildo? Especially when looking to purchase a strapless dildo, curvature and texture of the dildo should be the things you look at first. Many strapless dildos are specifically designed for g-spot and p-spot pleasure, so when you see that tell-tale curve towards the tip of the dildo, know that you're selecting a toy meant to hit those inner spots.
Other strapless dildos are crafted especially for orgasmic texture experiences that offer new sensations along every inch of the dildo. Try to think if you'd enjoy the texture that the strapless dildo offers before picking out your first strapless dildo. (If you've used textured condoms in the past, it can be a small indicator of whether you'll enjoy intense texture on your strapless strap on dildo - and what type of textures you happen to enjoy.)
