EVERYTHING I KNOW ABOUT SEX:
You have to make sure that she's female first. You can read about it in my "EVERYTHING I KNOW ABOUT WOMEN" article on the Internet.
The inside of condoms are greasy and
they're GORSS 
. Plus, if you have sex without the intention of making babies then it is considered a sin by both the Catholic Church and the Discovery Health Channel, so you're better off not using one anyway.
If you see hair between her legs then it is an obvious sign that she's trying to grow it to make a barrier around her vagina (THAT'S WHAT IT'S CALLED. I HOPE YOU'RE WRITING ALL THIS DOWN). What you have to do in this situation is make a surprise attack so that she doesn't catch on. A good way to do this is to wait in the bathroom until she comes in and then go for it.
For a change of pace, try finding all the holes in her body and see how many your cock can fit into. It should be at least seven.
You aren't
really supposed to wear clothes during a session (I KNOW, GROSS RIGHT?
), but I heard it's fun for you to take off all your clothes and have her leave everything on, and put a radiation suit on as well. It's fun, and
sexy to boot!
HOPE THIS HELPS.
