WooHoo

WooHoo is used in The Sims 2. WooHoo interactions can be carried out between two Sims, regardless of gender, that have a very high relationship score - so high, in fact, that newly-created married couples quite often can't even access it right off the bat without a little foreplay.

Sims remember all the Sims they WooHoo with, but it's also exceptionally likely to lead to jealousy in relationships. Sims will also have a memory of their very first WooHoo.

Where Sims Woohoo
WooHooing is possible in several locations:

Base game: Nightlife: Open For Business: Bon Voyage: Apartment Life
 * From relaxing together on a bed;
 * In a hot tub;
 * In a changing booth (Public WooHoo);
 * In a Car;
 * In a photo booth;
 * In an elevator;
 * In a tent; (Public WooHoo)
 * In a sauna;
 * In a hammock. (Public WooHoo)
 * In a helicopter
 * In a closet

Try for baby
A male and female Sim can alternatively Try for baby, if the female Sim is either on her home lot or on a community lot and controllable. Trying for baby carries a chance of conception depending on where it was done (60 percent if in a bed, 25 percent if in a hot tub, and 50 percent if in a clothing booth).

If your Sims are homosexuals, they can only have a baby by cheating. First you need to make them getting married/in one house. Choose the Sims that you want to make her/him pregnant Then use Boolprop testingcheatsenabled true cheat then spawn a Tombstone of L and D. After that, click on Tombstone of L and D; more; Get Pregnant with...and choose your Sim that you want to be related with. WARNING: Using cheats can cause errors.

Gender and Age compatibility
The following table shows the compatibility of various age groups and genders for WooHoo/baby interactions. Note that, when referring to trying for a baby, the table only states the possibilities for the interaction. As stated above, there are certain situations in which Sims who are able to have a baby together cannot try. It also makes the assumption, of course, that no hacks have been used - hacks do exist for teen WooHoo, and even teenage pregnancy!

Trying for baby is not possible for an adult female who is within a few days of becoming an elder.

As with all romantic interactions, blood relatives are automatically prevented from WooHooing. Furthermore, because of its wide-ranging implications, WooHoo is never autonomous.

Pets
Pets can WooHoo in order to breed (producing a litter of up to 4 puppies or kittens), but they require a Sim that has a good relationship with at least one of the pets to direct them, and obviously the pets must have a good relationship. The gestation period is approx. 72 game hours, just like Sims.
