This dildo is great! I originally ordered it to be used in a harness as a strap-on with my partner, and while I haven't had a chance to use it with her yet, I have had a great time using this solo! The thickness is just right if you don't want something too filling, and the ridges on the top of the dildo feel amazing, whether you want to take it slow or fast. As someone who is on the hunt for textured, silicone dildos, this one definitely fits the bill. I would say medium to light stiffness and very flexible at the base. Yay for body-safe pleasure!!
