Trouble

Hi, I'm having problems with both the hot tub and woohoo. For the hot tub, my Sims can't go inside it unless they're skinny dipping, like the option to get in isn't there anymore, which is a problem since I need to for the current quest. For woohoo, it's a different problem, the option to woohoo and try for a baby is still there, and my sims can suggest it, but they refuse to actually go to the place to woohoo at all, even if the other sim agrees.
