I cant add links or pictures to these posts so hopefully I am able to describe my question well enough. TLDR; Partner is ok with bi play, dildos, etc, wondering what the best option is per dollar value of moving dildos. Are “thrusting dildos” ok, or should you really pitch in for a full machine?

I’ve never posted much before because I am a very private person but I admittedly have been a part of some feminizing subreddits, sissy subreddits, bi subreddits etc. I have been with my partner about 2 years and I discussed a few of these kinks and also discussed which ones I want to explore vs which ones I keep solely to the internet for solo play (ie cucking, full sissification, etc). She joked about how she figured I was bi since she met me and was perfectly fine with me using dildos and anal play the same way she uses vibrators and other toys. Usually when I buy toys I like to pay in person with cash because there is no paper trail and to me leaves less questioning later from the bank, card companies, etc or others who track my activity (my mother unfortunately was on my bank account till I turned 20 and I was buying toys in college) However, I have noticed amazon has a bigger selection and is far cheaper than retail stores.

Anyways let me get to the f*ing point, no pun intended, I’ve used toys before and had hands free orgasms before from anal but I kind of want to kick it up a notch. With a stationary dildo, all I can really do is ride it cowgirl and suck on it a bit, its starting to feel bland. I want to feel actual motion. I searched amazon and found that there are thrust dildos with suction cups that move and are much cheaper and smaller(about 30-45$). However due to the small size and cheapness I am not sure how they compare to actual machines you see in videos, the actual thrust machines with robotic arms, which are about 80-90$ or more. On top of that, there would be the question of where to put it. I live in a 2 bedroom apartment so I can put it in the closet discreetly when not in use but with it being much larger I would still be worried of other guest finding it. Any advice on if I should just try a thrusting dildo on its own or go all in on the machine with a suction cup attachment?
