Yes... totally unnecessary.

If you can submit (and that's different from bottoming, which comes closer to Rag's description of his experience,) well and good, but only if it is something he would enjoy. If you're not enjoying it, then you won't understand it any better than if you had never tried imo.

If you really want him to gain experience at the hands of another, find a mentor dom... or an experienced sub, to help you two through the learning curve.
