OK, so I did some investigation.
Condom works on PLAYER CHARACTER ONLY. One piece is removed after sex. Preg chance is calculated accordingly to the slider.
Condom DOES NOT WORK on NPC. NPC do have their contraceptive chance slider. Trick is that NPC slider works regardless of condoms/pill equipped.
No need to equip your NPC with it, just use slider(s).
