My boyfriend is taking medication for high blood pressure which means that he finds it hard to sustain an erection but he won't agree to use a hollow strap-on. However, he became intrigued when I showed him this and refused to believe it was a girl's toy. He strapped it on and away we went and both had a great time as knowing he was satisfying me with the strap-on made him feel a lot happier about his inability to do so without it. The only comment we had was that the vibrator could have been a bit more powerful.
