If you have an iud, can you get pregnant when your boyfriend hugs you when you're both naked and there is no semen and no pre-cum present?

No: Hugging by itself isn't going to get you pregnant; however, one thing can lead to another and before you know it you are doing something that can result in pregnancy. Best Wishes!

IUD great: ChristinaR--If you've had an IUD, chances are you've been sexually active before. Generally, hugging--even naked--won't allow for pregnancy. That being said, even in the most fertile of women, IUDs prevent 99% of pregnancy. So you should be safe...Remember, IUDs do not protect against sexually transmitted diseases, so be careful still!
