If you don't want the ability to give birth, then you can get your tubes tied.
And no, I don't feel this way, my husband and I are childless by choice, but I can honestly say that I personally don't know any men who view women as just baby machines, nor do I know any women who view men as just sperm donors.
Are there men and women who are that misogynistic and misandrous? Yes, and it's sad and upsetting, but so is judging all men and women based on that.
What is interesting here as well, is that you seem to definite your ability to give birth, and since you hate it so much; your self worth, based on a misogynist view point. Why are you doing this? Why are you giving them that much power over you?
