Hey sipgirl, thanks for bringing up the topic

First off, yeah, I think many of us have some sort of experience with things like that, especially vaginally (less so anally simply because less women tend to experiment with that/enjoy it).

As for objects I've used on my wife: candles/candlesticks, bottles (coke ones are nice, long neck, as are wine bottles), vegetables (for added humiliation fun, make her prep and eat them after), ice cubes (although I haven't tried it, I'm told pouring water into a condom, freezing it, and then using the resultant ice-dildo is quite fun), various other things with handles.

The main thing to limit yourself on is items that could break off inside of you; I knew a girl that tried to use frozen hot dogs and one broke off, resulting in a hospital visit.
