The OP is looking for the option for Teen woohoo/pregnancy/etc in Life Stories.
We don't support teen woohoo mods here, including the Inteen
. If you have questions about it, they'll be able to tell you on Simbology where the Inteen mod is hosted.
Edit: To answer your question, no, Inteen won't work with SLS. The question is answered on Simbology here
Edit again: Jenna beat me to it.
