The potential problem with sex toys, dildos etc. I suspect (although if you disagree I'm sure you'll say so in your comments) is that your partner could prefer plastic to the real thing and that would be disastrous. Fancy how you would feel if you came second best to a dildo, especially a large one. I have no experience of this practice and would steer well clear as the risk is too obvious. One other point; I have total love and respect for the pussy and their owners and resorting to plastic, even for the best of reasons is a step too far and in my view is even disrespectful. Discuss!!
