Fall 2011, Several of the Christian Marriage Blogger Association scribes passed the hot potato regarding Birth Control Options and how some may affect sexual desire.
Since their information is top notch and the wheel does not need to be reinvented, I'm going to point you their way.
But first, just a tiny bit about my personal experience.
Our oldest son was conceived because when packing for a holiday visit we forgot prophylactics. One must remember in the words of my first doctor (who was a female), "Men's penises are like basketball players, they dribble before they shoot." So, I will whole-heartedly agree with Julie Sibert's Birth Control post, the 'pull-out' method may bless you. We brought home a little pumpkin 9 months after that Thanksgiving.
We continued with OTC (over the counter) methods until the birth of our twins. For the record, the twins were planned (at least one of them was) and not a product of birth control failure. I had avoided hormonal birth control pills because both of my sisters had problems with them. But, with three children within three years, I didn't think I could handle more children. We sought out the most effective form of birth control available, hormonal birth control pills.
I didn't have any catastrophic side effects, but I was a moody monster with NO libido. Plus, after two years of consistent use, I developed migraines. I coped for an additional year with migraines before deciding I was willing to accept the blessing of more children if conception took place while using OTC.
OTC methods were quite effective, mostly condoms, until the final freedom of the vasectomy.
Now, please see the following posts for more personal and indepth information regarding birth control options.
