you like heat well have a hot pan of water to soak your dildo in. Or want a little more heat try putting a little warming lube on your vibrator. Or if your daring, go get some tiger balm, now that well make things really hot. if you try it let me worn you a little goes A VERY LONG WAY.
Here is the other side if you try it hot why not put your toy in the freezer for a bit to chill it and try it cold??
