It worked! Thanks! :)

I was planning to pair up two childhood friends, but upon aging up to teen, the boy found the girl very unattractive. She found him very attractive and would flirt with him, but he always rejected her. I tried changing his preferences to match hers, but for some reason, his opinion of her has not changed. Please help! This is ruining my storytelling!

Thank you! I had no idea! I'll change the chance to a higher percent.

Hey! I'm having the same problem! My sims are not on birth control. I'm using the simple pregnancy mode. The percentage is 30% for both played sims and NPCs, but they've woohooed like 30 times. Both of them are played sims. I triple checked; one can impregnate and the other can be impregnated. There are four sims in the household. Both sims are human. 

Other things to note: They were able to get pregnant ONCE and they had twins. Also, none of the other sims in the save have issues getting pregnant. Do you have any idea what this could be? My guess was that one of them had accidentally gotten the hypofertile attribute, but I checked their sim info using your built-in cheat and none of them had the trait. 

Also, I tried having them woohoo with other sims and they didn't have a problem impregnating/being impregnated by the other sims; the problem only happens when they woohoo with each other. Please answer soon! I created this account specifically so I could get an answer from you!

Update: I've done some data mining. It seems to have to do with the percentages. When I set it to 40%, the sim gets pregnant 100% of the time, as do all other sims. When I set it to 30%, she gets pregnant 0% of the time while other sims get pregnant as usual.
