uh what. i find it more disturbing to think of non-muslims having multiple partners at the same time or reducing sex to something so meaningless without emotion. i hate this point used as an attempt to for justification. you've just made it all about sex too, haven't you?
other people can do whatever they like as long as they are happy in their situation. there is more than marriage to sex but most women could never be able to make peace thinking about their husband sharing that intimate connection with another woman/women. well, plenty of husbands feel that way too.

i do NOT argue...i just state my position which i just did coz arguments lead to nowhere. sorry**
