On the one hand, I can understand why people might want to do it. Everyone needs to get their thrills somehow, and why not get a bit of a lifehack by making a sex toys doll do things that it was never designed to do in the first place? Plus, if you’re a bit of an exhibitionist, vibrators then you can get a pretty good thrill by trying it out.
On the other hand, I think it still goes a bit too far. It feels like a step too far into the realm of dangerous and possibly immoral. It doesn’t seem to have any obvious benefits beyond pleasure, and the potential risks of injury and destruction of property seem too high.
At the same time, I don’t think there’s really a need to worry about it too much since there’s not a huge demand for this sort of thing. It’s just something that some people dabble in, but it’s not like a massive trend or anything like that. For the most part, it’s just a bit of weird curiosity that will never really take off.
At the end of the day, I think it’s one of those things that’s best left to those who are truly into it. I’m personally not a fan, but I can at least appreciate why some people might find it intriguing.
