A dildo is a solid and substantial erotic toy with a traditionally phallic form that does not vibrate. A dildo is not just for penetration, however. They are also ideal for tickling sensitive parts of the body and for external stimulation of the clitoris.
I've tested a fair few porcelain dildos in my time, and I have to confess that Dalia from Desirables is by far the best. Some of the previous ones have been hollow and more suited to external temperature play shenanigans with a willing partner. This one, on the other hand, is solid and feels much safer for penetration than others that I've tried.
