The majority of my toys are just for me. If I had a partner, and he was an occasional bed mate who wanted toys, I'd let him use the glass, or make him get his own.
There is no way in Hades would I use a toy at a man's house that he bought to use with various women. No matter the material.
I would be more than happy to borrow a toy from another woman who I trusted, but from a man who had toys at his house to use with other women. To me... that is just pushing my comfort limit.
Things like cuffs or nipple clamps I am not including in this, I am talking about insertable toys here.
