The Paraguard is a good option. There are no hormones, so it shouldn't affect your moods or sex drive. A few men say they can feel the stick, but it's very rare, especially in missionary position where penetration isn't as deep.
If you have heavy or painful periods, Paraguard can make them worse.
You do need to make sure you understand how it works as well. It's not an ovulation suppressor like hormonal BC methods. It's an abortive device. You could get pregnant every month if you have sex around ovulation. It works by thinning the lining of the uterus so that when a fertilized egg implants, it can't be sustained. Not a big deal to many women, but some believe that life begins at conception and that termination isn't ok. So I try to make sure women understand exactly how it works before they get it and find out later.
