Toys that work all the male zones. If there was a way to decouple the view that prostate play equal gay sex, that will be the breaking of the largest barrier to enhancing male pleasure
As I learned in therapy, the blessing that I had where oral and hand manipulation was "beaten" out of me. It took prostate play to break the spell.
Boy did it feel good, but it took time.
Toys should be had which allow men to get up to and close to the big orgasm, but allow the man to keep extending the pleasure.
