We continue practicing Karezza very happily. For me especially it is incredibly pleasurable and gets better all the time.
This morning I realized when I woke up in my room (we sleep separately) that I could easily feel a sort of version of that pleasure I feel with Karezza, without any penis touching or even an erection. It was not a penis experience at all.
By focusing on my root I could feel the pleasure in my whole body for an extended period of time. Not 1% as good as with my wife, but quite amazing nonetheless.
