Plenty of guys don't want to do anything you're not comfortable with....so you better be comfortable, amiright? If that means you have to drink so much you're practically unconscious, or swallow your revulsion, or close your eyes and think of Matt Damon, whatever it takes, it is your job to be comfortable. It is his job to be polite, to take it slow (he waited half the movie, didn't he? what a gem) and if all else fails, a little coercion never hurt anyone, did it?
