So, last month, as a Christmas present to myself, I bought a Real Body 3D onatorso (You Youjiang model, pictured), so I thought I'd take this as an oppurtunity of a review of sorts, more of the onatorso experience as a whole, if you're curious.
This was my first ona of this scale, but the first couple times I used it, I didn't care for it much, or feel much of a difference, but this is pretty typical of masturbators.
Around the fifth use or so, it began to get dramatically more enjoyable as it got used to me, to the point that I went from having a hard time finishing manually to finishing in a minute or two with the torso.
The pleasure ceiling is raised notably from sleeves, for sure.
And you're moreso fucking than jerking off, which adds a lot to the experience.
The combination of strenous exericse and emptying your nuts is a double-dose of dopamine.
The maintanence, the cleaning particularly, is a little rough though, especially with cervix areas.
Between all the lube and copious amounts of semen, it takes several washes before its somewhat cleared out (doubled if you used both holes), drying takes another 15-30 minutes for me, and then a thorough powdering takes about ten more.
Its definitely a process, especially right after you blow a sweaty megaload.
I do not recommend doing it before bed, because you'll be up cleaning it for a while afterwards.
Onatorsos are best for hot morning sex or an afternoon quickie imo.
If you're a complete NEET then the maintanence will probably be too much for you, honestly, and if you're particularly weak, then I can't recommend them either.
Its a lot of lifting and holding dead weight to clean them, not to mention if you want to do cowgirl.
The price tags are pretty steep compared to sleeves as well, definitely not just a throwaway item, which is why maintanence is so important comparitively.
I paid around $450 for mine personally, but you can get ones a good hundred cheaper at least if you're strapped for cash.
If you're considering getting a doll if all you've ever used is a sleeve, I'd recommend at LEAST getting a large hip first, just to see if you can handle the additional responsibilities post-coitus.
Both the pleasure and maintenance can be extrapolated to be much higher with a doll, so its more a matter of how lazy you are, and whether you actually have the space vs whether the pleasure is worth it.
