WooHoo

$$

WooHoo is used in The Sims 2 and The Sims 3 as a euphemism for sexual intercourse. In The Sims 2 the first time your Sim woohoos, there will be a comic animation involving fireworks.

WooHoo interactions can be carried out between two Sims, regardless of gender, that have a very high relationship score. In The Sims 3, Sims don't need to have such a high relationship score in order to be able to WooHoo. During conversation, the other Sim must find them "Extremely Irresistible" in order for the options of WooHoo and/or Try for Baby to appear.

Sims remember all the Sims they WooHoo with, but it's also exceptionally likely to lead to jealousy in relationships.

Play in Bed was present in The Sims: Livin' Large, as a predecessor to WooHoo.

Whilst "Woohoo" is probably protected, "Trying for a Baby" is unprotected, as your Sim cannot get pregnant because of a Woohoo. However, if your simmer 'Tries for a baby' for the first time with someone in The Sims 2, the memory that's added in the memory tab is listed as a Woohoo.

Where Sims Woohoo
The WooHoo interaction is possible in several locations:

The Sims 2
$$
 * In bed
 * In a hot tub
 * In a changing booth (Public WooHoo)
 * In a Car
 * In a photo booth (Public WooHoo)
 * In an elevator
 * In a tent
 * In a sauna
 * In a hammock
 * In a helicopter
 * In a closet

The Sims 3
In The Sims 3, there have been accounts of "Friends with Benefits", where two Sims could woohoo without become a love interest. In World Adventures, after you have installed it and the update, after a WooHoo, the two Sims will crawl out of the bed, think of each other, and pump their fists in the air while saying "Woo!". This means they had a fun time during the WooHoo.
 * In bed
 * In Military base (must Tour Base first)
 * In Theater (Must Tour Theater first)
 * In Science lab (must Tour Lab first)
 * In City Hall (must Tour City Hall first)
 * In a tent
 * In a Sarcophagus
 * In a Time Machine The Sims 3: Ambitions

Try for baby
A male and female Sim can alternatively initiate the "Try for Baby" interaction to conceive a baby. In The Sims 2, the female Sim must be on her home lot or controllable on a community lot. In The Sims 3, the female Sim does not need to be on her home lot to try for a baby.

Trying for a baby carries a chance of conception depending on where it was done.


 * 60% if in a bed
 * 25% if in a hot tub
 * 50% if in a clothing booth
 * 75% if on the Heart-shaped Bed

"Try for baby" is not possible for an adult female who is within 5 days of becoming an elder. In The Sims 2, "Try for baby" is not possible for a young adult female. Young Adults can "Try for baby" in The Sims 3 and Young Adult females are more fertile than Adult females; i.e. there is a greater chance for twins and triplets to occur.

If the lot already has 8 controllable Sims on it, the "Try for baby" option will not appear. Zombies, Mummies and Servos do not have the "Try for baby" interaction. Only heterosexual couples can try for a baby. Only adult females can get pregnant using this interaction. A male between the ages of Young Adult and Elder can impregnate a female.

Without cheats, male Sims can only be impregnated by Aliens, which occurs if they 'Stargaze' with the more expensive telescope at night for a while, but the actual chance of this happening is hugely unlikely.

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 with all romantic interactions, blood relatives are automatically prevented from WooHooing (though there are hacks that allow this). 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. If pets have a bad relationship with the other pet, they will refuse the action and go off on their own for a bit sometimes.
