There's plenty of things, like cucumbers, carrots, large pens. Got to be careful with all those, good fun but got to make sure you dont put them in too far. I just got my first anal toys and i gotta say it was definatly worth it . im a straight male by the way
I've tried all kinds of things; pretty much anything smooth and dick shaped. Cucumbers are an obvious choice and disappear from my fridge regularly. Popsicles can be interesting too! I tried a pickle once and it burned, even though washed it with soap and water first. Just be sure you don't get anything stuck in there and always use smooth items that won't tear the sensitive flesh inside.
