It's a shame you are in england and I am in NY, or I would gladly meet you for a very enjoyable evening of Pegging. Most men are insecure about their Manhood, (I would not have that done to me!) but rather they would like to be on the giving end,(LOL) as apposed to receiving.
My wife and I had only tried this a couple of times, before she became ill, it was a great feeling for both of us and I would hope that in the near future I would experience it again. Not only is it a loving gesture, it also shows your lover how much you trust her. I am a straight male, but I have enough confidence to allow myself to submit.
