Personally I would be worried about using an object like that anally because it doesn't have a flared base. You would need to be very, very cautious to make sure it doesn't get sucked up inside.

I agree with Dusk on the caution.

I haven't had that experience with anything that I recall. But, as far as why it hurts vaginally but not anally... I'm not a doctor nor do I play one on TV, but I can guess based on my own body & general biology knowledge. It's a bit like sticking something in your mouth vs. sticking it in your ear. It's not going to feel the same because the areas have different functions, different nerve configurations, and different amounts of flexibility.

I just couldn't bring myself to use these products vaginally or anally because they look like they would hurt way too bad.

I also prefer more texture for anal, in general! Weird how it works. Seems like my ladybits are way more picky
