I was 21 when i realised i didnt ever want to have children. I asked to be sterilised and was refused.
Ive been prompted to start this thread by seeing the different threads on contraception that have been on the boards recently. Im 41 now and still dont want children.
Im no longer sexually active with DH but have had 2 other partners in the last 18 years. One was long term.
The different contraception i have been on in my life are.
Femodene and Logynon Both of these are combined pills. This was between the ages of 19 and 21.
Norplant = contraceptive implant in the arm between the ages of 21 and 24. (Dh no longer wanted sex so i had it removed)
Depo Provera injection between the ages of 30 and 35 when i was seeing my ex OM.
And in the last few months the mini pill Zelleta.
Adding this all up in my head the amount of hormonal contraceptives ive been on in my life is .....a lot.
Ive known for such a long time that ive never wanted children. There is an article in Grazia this week about contraception and the wording underneath the sections about female and male sterilisation differs greatly.
Female sterilisation.
"for when the woman is sure she doesnt want any more children and has completed her family"
Male sterilisation. "for when the couple has completed their family" 
I just wish women were taken more seriously. Ive heard a lot of medical ppl say they wont sterilise a woman who has not had children in case she changes her mind. But many of us WONT change our mind. Is this a way to control womens fertility and sexuality? 20 years later i still feel the same about not wanting children.
