I'd encourage you to slow down a little and take a deep breath! My understanding is that your kids have little to no risk of contracting HPV from common household items. Here's a past thread very similar to yours where a moderator addresses the concern directly in the last post:http://www.ashastd.org/phpbb/viewtopic.php?t=4732
As far as your health, remember that even if your gynocologist does find warts or cervical changes, you are very likely to eventually clear the virus and be just fine. The fact that you're going to get things checked out just makes that even more likely, since you'll get treatment for anything out of the ordinary they find. Try to remember that this is a very common virus, although I do understand the stress it can cause. Best of luck to you, and as the mods always say, please post if you have any other questions.
