Spicy Romance Novel Question

Hey! So, as the title suggests, I am writing a spicy romance novel. This obviously is something quite popular in the book community, and I want to add something that I myself have never read in a novel of this sort. I have a new technique used during a smexy time between the MCs that I want to write into this novel, but I worry readers might not like it or will not understand. My question is, if I wrote a technique where instead of the love interest simply inserting a digit and doing the wiggle thing to hit a spot, what if they inserted, and did full on circles with the digit? I hope that makes sense lol. And to the moderators: if this post is not allowed, I am immensely sorry.
