nope. not in any version. but, young adults can (in The Sims 3 or if you have sims 2 university)
They can't have whoohoo
You Can't!! I know it really sux bt they can't have whoohoo
You cannot whoohoo with a sim in this game, only for the Sims2, that is it
You can't. The sims can't even kiss each other. :(
All you have to do is do whoohoo 2 times !
Make sure both sims are in love, then get them to relax on a bed. Click on the Sim you aren't controlling, and select WooHoo.
Make both sims relax in a double bed, then use one character and click the other then click WhooHoo or Try for baby. if you only have one character then you will have to make the other sim selectable {where you can controll them} by making them move in or part of your family first.
The game just does it by itself. so just wait and see . -_-
teen stuff teen stuff
To Woohoo, you have to do a lot of romantic stuff like flirting, then do 'make out' and woohoo might be available.
You go to a place with dressing rooms. Then you make one of the sims you want to WhooHoo go try something on in the dressing room. Then you click on the dressing room that the person is in under the other sim then you click WhoHoo! Hope I helped.
First you have to be in a relationship with the other Sim. Next, you make both of them relax on a bed. (If you are not able to control the other Sim enter the cheat "testingCheatsEnabled true" then shift+click on the other Sim and select add to active family or something like that). Next tell your Sims to cuddle. Then select whoohoo or try for baby.
