According to Bad-Dragon, their toys can be sterilized with a hospital's autoclave, which kills EVERYTHING bacterial. So as long as the toy is sterilized appropriately, there shouldn't be any problem. If the toys are unsterilized, that's disgusting... and potentially infectious if someone had a disease.

If people are disgusted about used but sterilized toys, then they'd probably be disgusted about sex with someone who's not a virgin, and that's... well, for the lack of better words... stupid.

If it were pure silicone I can understand it but bad dragon crap is tpr silicone hybrid rubber which is porous.
