How do I use dental dams?

I've seen the recommendations. I've seen the suggestions for do-it-yourself workaround (cutting open a condom, plastic wrap... ). What I *haven't* seen is practical usage advice — how to place the thing effectively, how to overcome the limitations of losing direct contact, how to arrange things to permit vaginal penetration with fingers while still maintaining protection and so on. Best-practice condom use isn't perfectly obvious either, but at the most basic level it's pretty straightforward. If you want to build acceptance for barrier use during cunnilingus, it needs to be at least as clear and/or at least as well-documented.


How can I ask my partner if they have any STIs?

I really enjoy reading your answers on these pages, but here's the question that I haven't seen addressed on your web pages or anywhere else on the Internet. Can you please suggest some appropriate ways to ask a person with whom you're about to have sex if he or she has any sexually transmitted diseases? A few months ago, I met a girl with whom I had sex... and, as I found out later, she had herpes. We did use condoms anyway, but there was still some risk in catching herpes since we didn't use condoms all the time.


Should I get a new IUD with each new sexual partner?

I recently had an IUD inserted. I'm not currently having sex, but wanted to be prepared as I am seeing someone who I may become sexually involved with.

My concern is I was told the IUD would need to be removed if I had sex with a partner and then changed partners later. This IUD is a 5-year IUD and the cost was quite a bit. If I have sex now and then stop for a year (or any period of time) and was to become sexually involved again with another partner, why would it need to be removed? If STDs are not an issue, does it still need to be removed?
