No Romantic Interactions besides 'Offer Massage'

You say you have no mods/cc. Usually this IS mods related so, did you never have mods in or remove them ?

Also do you have the issue for every couple or just one ?

I have never downloaded or used mods/cc. I may have innocently downloaded cc through the exchange. I did check, and I had a mod folder, but I have since deleted it.

In reference to the second question, the problem is currently with one couple. I had them break up, and the one sim started a new relationship with a brand new sim. I had no problem, but after a while, the problem occurred again.

Could you check on the sexual preferences the Sims with the issue have ?

You can't get cc through the gallery. 

I am having the same issue. There were no problems until I aged up our science baby. Now he is an infant and all our interactions are gone.

To be sure, you're not using mods/cc ? Could you add a pic of what you are seeing ?
