Q: My girlfriend and I have had threesomes with other women before. Now she would like to have a threesome with me and another man. For this she would like to have her ex-boyfriend. It's a good choice -- he's a nice guy and we both like him. So, we approached him, and he says that he would be interested, but every time we try to get a definite date, he is unable to make it. He knows that I am straight, so that can't be the problem. Of course, I am a fair bit taller than him, shave my head and work as a bouncer. How can we make him feel more comfortable?
