Who do tu think is más faithful/likely to cheat on their lover, the female o the male?

Are tu kidding me?...Honestly, no gender is más faithful o likely to cheat than the other. Cheating isn't a mistake. It's a choice. So is being faithful. tu can choose to be faithful and respect and amor your gf o bf, and tu can also choose to not care about their feelings and break their corazón and cheat on them as if it's nothing. Guys cheat. Girls cheat. Some girls can be heartless sluts and choose to hurt their boyfriend por going for some other guy, and some guys can be douche bags por choosing to break their girlfriends hearts and go after some other girl. But not every guy is like that. Not every girl is like that. And their gender shouldn't be compared o blamed for the amounts of times that person cheated o is más faithful. The thing that makes them a cheater o faithful is who they are as a person. Blame their horrible personality for cheating, not their gender. Blame their kind soul for being faithful, not their gender. Basically my point is, cheating is up to the person. Anyone can do it. It just takes the right person not too. Being faithful is up to the person. Any person can do it. But it takes the right person TO do it.

It's equally likely for both males and females to cheat on each other.

I agree with @seastar4374 It could either be the male o the female.

Same. Both can be just as sneaky and low as to cheat on their lover.

statistically speaking, I think studies have generally shown that men are más prone to cheating. there's obv a lot of variation on an individual basis etc. but stats don't lie
