You can't unless you own the PC version sorry.
The Sims 2: Castaway is an expansion for the original game on the PSP where the Sims are shipwrecked. You can do woohoo in the game.
On the Sims 2 Castaway for pc you can have children if you follow the storyline all the way through and then go into freeplay. If you are using Sims 2 Castaway on the Wii then you can not have children or even woohoo.
No you can't sorry :(
Yes! You can do 'woohoo' on everything, except on the ds version!(stupid people...) Hope i could be of help! Except you can't woohoo on Sims 2 Castaway.
