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?


What should I do if my girlfriend's afraid to have sex?

My girlfriend and I have been going out for more than two years now. I am a first-year student (18 years old) and she is 17. We haven't had sex yet, but during the last year and a half we tried pretty much everything there is besides it. I really feel this is the right time, but when I try to talk to her about it, all she says is that she is afraid. She says it is not that she does not believe in losing virginity before marriage, she is just afraid. I don't want to pressure her, but I just feel that maybe I am not the right person for her or something. What should I do? Thanks.
