Is Monogamy unnatural nowadays?

Morning friends, how are you doing? Yesterday night few of my friends came over and we discussed a very interesting topic. Can a man really love and be faithful to one woman? Our opinions have split. Some of my friends said that once a man gets a real woman he won’t want to sleep with other women and will be forever with ONE. There are lots of loving, faithful men out there. Another opinion was - Monogamy is unnatural for men and any guy will cheat. Guys, can we love and be faithful to our partner forever? Do you think all men cheat? I want to know what do you think on this meter.

is monogamy unnatural for you?
