[LS] LE/Reset when trying to do romantic interactions

I am having the same issue. My legacy family sim was a teen when I got lovestruck and now she is a young adult and not woohoo. The game lets me pick the action, she gets an increase to her romance but then the action cancels. I can not try for a baby or anything.  She is 100% friendship and romance with her partner and woohoo is stuck in glitch. No Mods.

The same thing is happening to me on PS5! Obviously no mods, I haven’t even turned on cheats because I wanted to unlock the achievements. All I have is the base game, city living, crystal creations, and now lovestruck. I made sure the bed was in the middle of the room and a hot tub with no luck. The start the action with giggling about it then they just stop. I can’t get them to cuddle in bed, woohoo, or try for baby

To fix this issue go into MC Command and delete the sims relationship with each other and then go back and add the friendly and relationship levels to the highest setting and it will work!

I am also having this issue since Lovestruck but only for one Sim that I am aware so far.  I did purchase Lovestruck but this Sim was a teen until recently so he could not woohoo previously. The older sims in the household can woohoo.  I moved the Sim to a new place, and he invited his girlfriend over who is also a young adult, and they cannot woohoo in the bed or the hot tub or anywhere. They get excited like they are going to and then just nothing.  It makes me sad. They are young and in love. I do not play with mods or custom content.  I did get a message that described their relationship as wholesome.  Do you think they have to get married first? 

Same here (playing on a Mac)! No mods installed and have the same problem - still after the most recent update.

Teenage sims were able to woohoo (or however they call it for them) - when they aged up it didn’t work anymore. While the adult sims in the same household can still do it.

Really annoying.

Hello, I'm still having this issue. I have no mods running on my PC.

this exact thing is happening to me too. after 2 teenage sims aged up into young adults it seems

I have the same issue. I tried to create a club and set woohoo as an activity, this didn't work. Then tested the club with a random sim I met in and I was able to woohoo. I think it's a romance dynamic / sentiment or romance level issue. Just my two cents, I hope this gets fixed soon. 

I tried the MC command center fix mensioned above, it didn't work.
