It's because they think it's Catholic contraception, so if someone gets pregnant, that means it failed. If you have 5 kids and practice NFP, then they be like,
Damn. Their NFP broke 5 times, y'all.

If you told most guys that they'd be abstaining for X number of days per month, but could have sex every single day other than that, and their wife would probably go along, they'd be like,
