Not yet into Estim. However l have been into anal stimulation with dildos and sizes up to 3 inches in diameter . I like the idea of ghost fucking and not yet decided on proper size for this. Going to start cheep with power box perhaps a 7000 tens. Just to try things out. I was thinking that a 2 inch diameter probe might work better for me considering sizes of anal plug smaller than 2 inch diameter slip out. I have seen lots of good reviews on the moaner and it’s diameter however it is smaller than 2 inches. Do any of you have other thoughts, or experience that could direct me for the proper size to get good effect for a good ghost fucking probe?
