Honestly i was worried it all wasnt going to fit at first and I'm pretty amateur when it comes to anal but with some lube, time, and analeze it all fit and was pretty comfortable! The texture was more enjoyable than I thought, but my only issue is that the soft silicone is a little difficult to use force on. For any other toy, like the sentinel, they're just fine with force and supporting themselves, but I guess because of the lack of support, the Vine depth trainer falls over and bends on itself (it isn't a huge issue it's still perfectly useable, just an aesthetic issue). Overall, it's fantastic and really recommended, even for beginners!
