Why is a woman's reputation always tarnished whether she cheats, is the mistress, or isn't a virgin anymore?

Though there is still some double standard; lesser than years ago (at least Tiger Woods' then wife went after him and not the other woman) but it still exists. I've even seen the Spanish version in soap operas; always shaming the woman. She didn't do it all by herself. The man was a willing participant too. If a girl's HS boyfriend cheats, she blames the other girl for stealing her guy. How about blaming the guy?

If two students have sex for the first time and rumors starts spreading at school, it's always the girl signaled by classmates. She didn't have sex alone.

If a girlfriend or wife cheats, most of the times the man kicks her out and breaks up or files for divorce. He is correctly more angry with her, not the other man. There isn't even a term for the male equivalent of the homewrecker (aka la roba maridos in Spanish). However, if a boyfriend or husband cheats, the woman wastes time taking her anger on the other woman and the mistress' reputation gets ruined. So it's a lose-lose for the woman, whether she's the cheater herself or that participating mistress. It's always her being gossiped about. If the cheating wife has a daughter, the little girl's reputation gets ruined just because her mother is a cheater. If the father cheats, his children's reputation do not get ruined. Why is only the woman blamed and hold to a higher moral degree?

No body steals a woman's man. He is grown enough to have self-control too and not cheat. I've seen this in a Spanish soap opera, where two lovers were going to abandon their families. Both died and everyone in the small town kept endlessly talking about the man's cheating wife nonstoppable, no one bothered to mention about the cheating husband. A husband that cheats and abandons both his wife and child is just as horrible too. He was still well respected in the small town. The women themselves are willing participants of shaming the woman too; enablers fo that double standard. Why is that?

Personally if a man cheats, my anger would be directly at him. He's the one I was in a relationship or married to, not the other woman. He was suppose to say no even if the woman tells him to cheat on me. He's no a little kid that can't control himself.
