Yes, men are more likely to cheat DURING pregnancy and shortly after.
Why? Because of all the hormonal changes, many women may not feel like having sex at all, and after giving birth it takes time for the vagina to shrink so it can receive a penis.
I'm not at all surprised though, because society does not teach sexual discipline. In fact the opposite is true, if you aren't out here having sex than something must be wrong with you.
Why should a man not be able to get sex if his wife isn't giving him because she doesn't feel like it from pregnancy hormonal changes?
Nah, but real talk. Most women don't want their man watching porn and masturbating, and on top of that he ain't having sex with you. And y'all want this to go on for what 11+ months? The whole pregnancy and after giving birth?
The vast majority of men have either been busting nuts in their hands or in some p*ssy, so this ain't a surprise at all. Men aren't taught sexual discipline and the importance of it.
