Re: If you could be married to more than one guy at the same time..
if a man is nikkahfied with 4 ladies, then it is ok to sleep with one at a time.
i dont see any islamic prohibition as long as husband can fulfill the rights of each wife.
now the concept of threesomes is not supported by teaching of Islam.
Ibless khabees(satan) is the one who implanted this idea into human minds.
