Strangest thing you've ever used to masturbate

Wondering what the "strangest" thing people used to get off with. Mine was probably a banana peel. I think I was a 15 yo virgin. VERY horny. Had just eaten a banana, and thought "no point wasting the empty peel". It got the job done, but never did it again. My first gf told me she used to get off as a teen by rubbing her crotch against a clothes dryer while it was running. I wish I could have seen that.

With me, it was a salad cucumber ages back. I hollowed it out and had a pretty realistic feeling in "her" 😃

HMMMMM? Is humping the bath tub edge strange? I do this.

I used the central part of a water filled parasol / sun umbrella to masturbate with once. The part that the umbrella pole went into was quite long and wide enough for my erect penis to fit in. It wasn’t the most comfortable way to climax but it did the job.
