Natural Family Planning aka symptho-thermal method?

Hi there!
I'm just wondering: are there people around here that use Natural Family Planning aka symptho-thermal method?

I've been an active user for about 2 years by now. Since I don't know anyone else who uses this method, it gets kinda lonely ;) I'd like to exchange views and experiences. Questions such as:
-how do you feel about using this method?
-what are your reasons to choose this method?
-to what degree is your partner involved (or do you feel comfortable with)?
-how does it affect your relationship (both pos and neg)?
-what sources did you use to learn this method?
-do you combine with other methods of contraception during your fertile periods or not?
-etcetera

For those who do not know what this is, I wouldn't want to make this an ununderstandable thread :)
NFP is a method in which a woman observes her body daily, records findings and analyzes them, to determine when she is fertile. It can be used as contraception as well as pro-conception. There are a lot of 'natural' unreliable methods that gives this one a 'bad' name. However; the method as described is based on scientific research (mostly in Germany) and is sometimes referred to as NFP-DAG. It has a pearl-index for 'practical use' of 2 (which equals 2 women in 100 becoming pregnant after regular sex over a year). This is about the same as the pill (see Brandye's topic:

O, and men who use the method in their relationship are most welcome as well!
