Sounds like it just needs to be opened!
Rez the object onto the ground, right-click, and select 'Open'
I also suggest working on some freebie AO's so you can get used to it all.

If you want a male AO you can try this. Never had it before though.

Like I said, pick up some freebies one and get the feel of it. Then you can try it. It might make you feel better.
