Wow, your post has taught me something, than men’s sexual responses can be as varied as women’s! I have a lot of gang bang fantasies and really get off most from reading these stories, but I have to say I did not resonate with any of the reasons you stated. For me, it is knowing that the women sandwiched between two men is a real, separate and non acquiescing person who is not being corrupted by a man, but is herself a truly separate sexual creature with needs of her own. It is interesting to see how different a place another man can be with the same fantasy.
