What is everyones preferred forms of birth control?

I am exploring different options. I won't go back on the pill as it caused way too many problems for me and I think contributed to my cervical dysplasia.

I am no looking into Lady Comp and the Fem Cap. Lady Comp is similar to charting but it does all the work for you. You can also start developing a history of information (up to 15 years) that you can use later when trying to get pregnant. If you are trying to get pregnant it can also help you conceive a boy or a girl. It's expensive but looks really cool.

Also since I have issues with that region I would love to know what people found in their experience and what was the least intrusive or irritating. I even worry about lubricants, spermicides, etc.
What has everyone's experiences been and what do you prefer? Are there natural lubricants, etc.
