Biofeedback devices or apps and the pelvic floor

(Please move to Sexual Health forum.)

I have become more interested lately in deeper sexual experiences. Thanks by the way to everyone who has posted some amazing threads in this forum regarding sexual health and learning.

In that vein (OK - go ahead and have fun with that reference), I see that there are biofeedback devices designed to help one strengthen the muscles of the pelvic floor. Traditionally, I suspect that they are marketed and designed to deal with incontinence for women, but I am wondering if anyone here has any experience or thoughts about using them to help men control their ejaculations?

Thanks!
