That sucks. No offense to anyone here, but just the fear of this kind of stuff is why I never attend anything that is just groups of men. When I was a teenager, I went on a bus tour with my church's men's group to a major city for a Promise Keeper's conference. As the bus crawled through downtown in heavy traffic after a car accident, these grown, married, church-going men were hooting and making obscene comments to the obviously underaged prostitutes on the corner. Even though their vulgarity was not directed at me, I felt like a trapped animal surrounded by hunters. I've never attended anything that was men-only ever again, and I doubt I ever will. I know that is mostly paranoia but its how I am.
On a practical note, maybe it would help to write a letter to the directors of the conference. You never know, it might spark some changes or an awareness for greater sensitivity.
