I just saw the video. It doesn't look like a positive sexual experience. The lady was being used as a tool with a high degree of forse. It's too bad this happened like this. I'm a firm believer in being a giver and being a receiver. You hope to feel good about giving and the same about receiving. It should be a caring experience and enjoyable for all who participate. Do a search about Tantra and you can learn more about making sex a positive experience for all who join in and those who enjoy watching. I would not like to see my wife used like this and she would not allow it as well. Perhaps your friend (the guy), enjoys this type of sex. Perhaps he just doesn't know what a caring relationship is and having not experience one, doesn't know the difference. I wish you more positive experiences and hope that is one doesn't put a damper on your relationship and moving forward with a sex-positive lifestyle.
