Definitely protection (and remember that two condoms are worse than one. You can't wear two at a time no matter how safe people think that might be. The latext-on-latex is likely to break them).
Make sure it's the right place. That is, make sure <b>nobody</b> is going to come home in half an hour, make sure neither of you have to be somewhere soon, make sure there will be NO interruptions. That'll ruin the mood like you wouldn't believe! Turn the lights down, turn off your mobile phones, and take as much time as you want
