Why would men cheat on their hot girlfriends/wives with a much less attractive woman? Asking for a friend.
So, about cheating down. I’ve heard excuses like, “Because she’s available. Had to do it from the back otherwise I wouldn’t be able to get it up lol. Nothing more than a cum dump.” Or “Because less attractive girls have lower self esteem and thus are easier lays.”

Someone mentioned it, and I’ve heard this excuse as well, men cheat with someone who’s a downgrade because they’re insecure about themselves, because they think their women are out of their league, so they will accept validation from just about anyone.

Another excuse, because he needs an ego boost and someone “beneath” her probably feels grateful for the attention and makes him feel better about himself.
Also, as simple as because he was thinking with his dick, and to him, it was nothing more than a little upgrade to masturbation, especially when he feels so ashamed and disgusted with himself right after he’s done.
