Trying a different toy

I own a Helix, and was wondering if I should try a smaller and more filling model like the progasm jr.? I was reading on the Aneros Reddit and someone mentioned that if you own a Helix, and push it in farther and then you feel contact with your prostate- you need a larger model.

Same goes with if you slightly pull the Helix and feel contact with your prostate- in which you might consider getting a smaller model such as the Progasm/Jr.

I am in the latter boat (experience contact when pulled), and was wondering if I should try the Progasm Jr. ?

I have owned the Helix since Nov 19' and experienced some minor p-waves once.

Thanks!
