lol rich, i'm counting my blessings.
there's an old bluegrass song called pig in a pen that doesn't specifially portray men as pigs but the chorus does seem to indicate that the author may posess a bit of the porcine element. it goes:

i gotta pig a home and a pen,
corn to feed him on,
all i need is a pretty little girl,
to feed him when i'm gone.

i don't have an answer to your first ? carol. don't know why a hetero male would say that. the phrase "men are such pigs" is fairly common where i come from and is usually uttered, lightheartedly, in mixed company by one woman to another after a male in the group has made a sexist remark, told an off color joke, had a gaseous emission of some sort etc.
an emphatic no to the second ?. i often counsel my male friends that they have to be sensitive,caring people these days or they'll never get laid *g*. dave
