Hey Christine. We use a pillow case folded in thirds long ways if that makes sense? We haven’t had any complaints about modesty yet. We start with placing it in CT though and explain why we need so much skin to show.
We place pillowcase over genitals and then cut it out of our ROI. Works well for us. Let me know if you have anymore questions!
I’ll work on getting a picture up of an example ROI.
