If god wants us to be with only with one partner?

how come we're horny almost all the time and we men are often want to just bang on any women. i know you priests, pastors, and monks... you people are the even filthier. i know when you see a woman walk around with tight azz jean. you just wanna bang that mofo azz hard. we men are like that the more you suppress the more you become a beast.
