So? The man's genitals didn't decide to rape her. They should still be removed. Edit: From her, I mean. He should not be castrated unless completely necessary.
Then you cannot claim that by consenting to sex you consent to the risk of pregnancy. Therefore, if pregnancy is not consented to, the fetus is violating her bodily sovereignty without her consent and should be removed.And yes they have to be consented to separately, hence it's two consenting partners having sex.
No foetus has consented to an abortion, I would think.
And if the man does not consent to stop? Should he be allowed to continue?
