If you like someone and want to make them happy or something, then that's your internal motivation and reason, meaning it depends entirely on you, your relation with other person and your own morality. If it's external motivation like money then there you have already shown that your morals can bend to external temptation, meaning anyone with enough monetary incentive can tempt you into cheating. It simply makes success of 3rd party involvement much more likely.
Another reason is tied to partially why men avoid sluts or serious relationships. Imagine you marry one, have kids together and one day your kid comes from school sobbing and tells you his mom is whore and that other kids in class has shown him vids of his own mom getting plowed and taking cumshots to the face. That's the big one, but there is also other ones, like other men simply pitying you because they were first. While about the latter you may not care, it was risk you took when you got together with a slut, the former is passing consequences on your kids who did not do anything to deserve it. Now think which is more likely to be involved with more men in the past: slut who does it for fun and does it with her group of friends or is chad exclusive, or hooker who will agree to have sex with anyone who meets some basic hygiene standards?
It's also the reason why porn or anything involving face is much worse than anonymous attentionwhoring on /soc/ with faceless pics: when you get your face involved, your past will always be tied to you and will follow you, while faceless nudes, even if posted for completely vain reason, have high chance of not being consequential.
As I've said, I'm degen myself so I can understand why people would slut around, I wouldn't mind femanon who posted faceless nudes, I could even take some with her, but at least do it wisely.
