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.
Like a spent gladiator
crawling in the colosseum dust
who can count on his remaining limbs
all the people he can trust.
Like the one who stands behind him
cheering him on
Estatic when he stands defiant,
wild with abandon when he's gone
just stay alive.
do whatever you need to.
you are worth it.
