Quesions!

Ok, So I'm not a Sims newbie, but I've never really delved into the world, just played it for hours on end. I am, obviously, a Mac user, why else would I be on this page? and am wondering where I can get more Mac custom content (I only have Open for Business) I must have know before, because I used to have a lot of custom content before I uninstalled it. I also used to have the ability for teens to woohoo and have babies...but I can't find that for Mac now (does that include teen/adult relationships?) AND what is the WooHoo thing at the top of the page? I don't quite get it...

last question has nothing to do with downloading, I was playing the Pleasants and had the maid move in, and Daniels wife (forget her name) also fell in love with the maid (also forgot her name) so it was a big ole love triangle. Well the maid got preggers then had woohoo with the wife, then promptly got up and died! I was able to beg for her life, but it was so weird and random...anyone know what happened?
