These dildos try to replicate real male penis as closely as possible. And in terms of shape, length, color, veining, glans, even testicles are often found in these dildos. You’d be surprised, but coming across a toy that has men’s testicles just has something that is very racy (or over the top as far as it goes). Materially, these toys are either silicone or TPR/TPE variants for the most realistic imitation of a penis.
