I've never heard of this syndrome before.

I masturbate on average about once a week, maybe more some weeks, and less others, and I normally do it prone on a pillow.

I've not encountered any of the problems mentioned here but now I am concerned.

I'm also concerned about sexual practices with women as I often finish prone lying down on them and rubbing against their stomach, thighs or buttocks.  Could this create the same physical problems described here?
