Sorry guys I have been very busy but I would like to add some information here.
First, there is no contraception method that is 100% effective and 100% without “disadvantages”
Every method - none excluded - has advantages and disadvantages, and we still don’t know much about the long term effects of many methods.
But choices do exist. Each one of us can decide what our priorities are. There are advantages and disadvantages to each method, bar none. Other lifestyle choices are also involved, and will influence our choice of contraceptive method. The first step is to obtain complete information.
A distinction should be made between methods to prevent conception and those for spacing (distancing) the birth of children.
The so called “natural methods” are many, and are practised with success by a large number of people. They include, besides the rhythmn method which is highly unreliable, also the Billings and Ogino-Knaus methods which rely on body temperature and cervical mucus examination. Some of these are highly sophisticted, for example the computerised “persona” method (it uses a small hand held computer I believe using urine, but I’m not sure about it). I do know people who have used these methods with great success over the years. Not only does it permit you to avoid conception, but it also allows you to target the most fertile period and get pregnant - though I don’t know how reliable it is about choosing the sex of the child. This method, like most other “natural” methods, requires collaboration on the part of the husband. I believe that there are centres where they are taught and there are qualified teachers all over the world.
As a child spacing method, recent research has shown that demand breastfeeding is a reliable method for 6-12 months - This is known as the “Lactation Amenorrhea Method” and there are entire books dedicated to teh topic.
Then there are other contraceptives - the male condom and the female condom (new, but it exists), the coil or spiral or IUD (some are combined with hormones), the diaphragm (barrier method - still used extensively), plus several other variations of the barrier method (cervical cap, etc.)
Hormonal methods are the most recent addition to our list of contraceptives. There are several types of pills for women - the combined pill, the progesterone only pill, etc. and there are also different doses available. “Depo-provera” is the name of one of the injectable versions. The patch is the latest version of this.
Unfortunately the male pill is slow in coming. There is still a lot of talk and much diffidence about it.
Methods such as vasectomy and tubal ligation (called incorrectly on this thread as female vasectomy) are considered, for all intents and purposes, permanent and irreversible although there have been cases where they have been reversed.
Personally, I have great reservations about hormonal contraception. I do not trust the industry, who funds almost all the research in this field to tell me about the side effects. And they cannot have any way of knowing what the results will be in 30, 40, or 50 years’ time. That will take generations of women who have taken the pill before we know more. I do not want to be a guinea pig for contraceptive research. I am willing to take the responsibility for my health and make choices that I can understand as far as I am able to understand them. And I am willing to take a litte extra trouble to do so.

I wonder why women (or men) want to have a a method they don’t have to think about? Although I don’t want to worry about it I do know that any choice I make has risks and advantages. We all know we have to take responsibility for our life choices and this is one of them. Neither men nor women are sex objects even if sex is an important - and enjoyable - part of our lives. Sex should be a responsible act as well. The responsibility belongs to teh man as well as the woman. By showing consideration and sharing responsibility the life of a couple can be enhanced.
