Kinda? It's not exactly like that, but close enough. You can always stick something up there and get a feel for it yourself, ya know.
Edit: So I can't stop thinking about this and had to come back to this post: Does it feel different for a woman? Like, they don't have prostates, so would anal not feel as good? Or is the G-spot/skenes (whatever that raspberry feeling chunk of nerves inside the vagina is called) situated such that it's more or less the same? π€
Or you could just find yourself freaking out at 7am with your arm up your ass all the way to the elbow trying to grab that cute heart shaped buttplug that was way too small and somehow just kept crawling further and further up your ass while praying that you won't have to go to the ER. That's cool too.
I'm not opposed to the idea but it doesn't seem like the kind of thing you can just try one time. Isn't there some kind of preparation phase to be able to handle ..."stuff"?
For 2. spend the time and do a "spot" test similar to laundry detergents. Some lubes can be very irritating and burn (usually the really cheap ones). It can be somewhat confusing because both the physical stretch and substance irritation feel like a burning sensation.
I personally prefer silicone-based lube for back door play. Lasts a LOT longer, doesn't get sticky (can get dry, but nowhere near as quickly as water-based, in which case, just apply more lube,) and the overall glide just feels better imo. Clean-up is a little bit more intensive. Just a light scrub with soap and warm water, instead of a quick rinse or wipe. Toy play is a good warm-up. Just make sure your toy is specifically compatible with silicone-based lube or else you risk major problems.
An acquaintance of mine had his prostate removed due to cancer and he confirmed that butt sex no longer feels pleasurable. I imagine it's the same for women.
