why cant my sims sleep together

@Nootsdoots, there are several reasons why this might happen.  (I assume you mean actually sleep and not woo hoo! ) Often their relationship is not high enough for them to feel comfortable to sleep in the same bed.  I have (several times 😳 ) accidentally made a couple I intended to be married but forgot to click on that when making them in CAS, so the game just assumed they were roommates.  When I went to play them, they wouldn't sleep together because they didn't have a high enough relationship to sleep in the same bed.  😞  I can't remember if it was the Friendship meter, the Romance meter, or both that affected this. I used to fix this with a cheat, but a lot of cheats of this nature don't work anymore (they have been disabled) so I haven't been using these types of cheats in a while.  I need to check to see if this is one of the ones that doesn't work anymore. 

Another common reason why two Sims won't sleep in the same bed is because there might be something in the way of one of the Sims that prevents them from getting into bed.  I have a relative who started playing TS4 on the Xbox and she couldn't get her married couple to sleep in the same bed or woo hoo.  I noticed their bed was up against the wall and when she moved it there was no problem. :eahigh_file: Sometimes also I will download a house (I play on a PC) from the Gallery and there is a decorative object or other piece of furniture in the way of the Sims' path to the bed and they can't use it. This usually happens if they use the Move Objects cheat when they created the house.

If neither of these possibilities are your problem, then please tell us so we can try to figure out what else might be going on in your game! 😉

Best of luck and Happy Simming! 🥳
