I think it is most likely that a complete Mini Sex Doll robot will be developed in Japan as the ultimate functional synthetic companion. I don’t know enough about robotics to predict when it will happen. But I can foresee that owning and maintaining the first functional robots would be expensive, so they are likely to replace dolls at doll hotels in Japan because most people can’t afford them initially. You might be interested in finding topics about robots in the General Discussion. This has been very helpful … understand the point of view … ask more correct questions … it’s not that I didn’t do any research … I might read too much. I started to get more confused. But this may be a good thing. So I want to start thinking about features again. Weight requirements … See I really don’t know. When I was in my 30s, I was a healthy man … I was running and lifting weights. I’m 6’2 “. But it’s another thing entirely … I imagine … it’s like handling heavy Japanese Mini Sex Doll in bed. I read that nothing really prepares you for this. So consider My physical condition and requirements.
