I am not worried about that too much as we have great sex. and I am above average in size so I don't believe this would happen all though its not totally impossible. I just love the look or her face when she is enjoying herself during sex and Id like to experience that while not actually doing the work and Id love to join in at some point as she would look amazing with 2 cocks....its really about her enjoyment to be honest I love seeing a woman pleased
