Advice: Strap-on dildo
From wipipedia.org
The ultimate tool for power exchange.
A strap-on is a harness that attaches to a dildo. It allows a woman to have an artificial penis, and gives men the opportunity to double penetrate their partner or simply use it in place of their own penis.
They're also bloody hard work (and gave me more respect for mens' abilities).
A good source of strap on harnesses and helpful experienced staff is shh womens sex store in East London. http://www.sh-womenstore.com/
