Has anyone used thrusting dildos here that isnt too expensive?

I want to use something that thrusts fast inside me. Ive currently got one.that i ordered from best vibe but it isnt so intense. I want to be able to attach it somewhere. Im wondering how i can use it when im in the bathtub like the best positions. I crave dick but my husband has a low sex drive and also told me.that he just doesn't think about it. So i want to please myself lol
