All abortions are the result of unintentional pregnancies. Only a small percentage of them are the result of rapes. What about that is confusing? And insemination can only happen when a man ejaculates. A woman can have an unlimited amount of sex and as many orgasms as she wants and never conceive. It is only the irresponsible orgasms of men that lead to pregnancy. Again, what about that is unclear?
Both men and women should exercise care and good judgement if they want to have sex without pregnancy, but right now, all the burden seems to fall on women, when in the most literal sense, all unintended pregnancy is due to the ejaculation of men.
