I have. We have recently bought and started using some stainless steel toys. They are very good for temperature play. Cold definitely is a nice sensation.
For years I tried to get my OH to give me a BJ after slurping on some hot tea, but to this day I’ve been left sorely disappointed. I might trade her in.
( I did once decide wanking with a beer glass full of snow was a good idea. Like a Fleshlight sorbet.
It wasn’t )
Never tried this but now I want to . I have a glass buttplug and my beloved njoy wand. The feeling as it goes in cold is sensational. Best go clear a space in the fridge.
I like the idea , but have no idea when I could do it . Depending on how bad a day my wife is having , she might hate the idea or decide it is disgusting .
Over the years former girlfriends and ex wife and current wife all went down on me with ice cream or milkshake . OMG ! I absolutely love it . Conversely , they all enjoyed me licking , tonguing them while I am eating ice cream or even drinking a cold beverage . Warm of hot never really did it for me .
