I'm not asking how it's done, just how YOU prevent? I know how to NOT make a baby…

Do you use condoms? Pull out? Refrain from sex?
We might be going to Hawaii in January, and I would really like to be able to go. It's a work convention that is always held in January, and for the past 5 years has been in Deadwood, SD. This year they might switch it up. I've never been to Hawaii and I'd really like to make it a little vacation! I've charted on FF before but I wasn't very good at it. I thought we totally missed the window the month DS was conceived… and well, we didn't! So I'm obviously not very confident in my charting skills. So, what's done in your house?
