This question is mostly towards the pro-choice women out there.

Assuming the statement means exactly what it says at face value, consented to have sex with someone does not mean consent to taking on the responsibility of being a parent. Keep in mind, the statement is about opting out of parenthood, not pregnancy specifically. You can give birth to the child and still give up the child through adoption or at a fire station.

So my question is, why should this philosophy only apply to women and not men too? Why shouldn't men have more options to opt out of parenthood if they decide that's not what they want after sex has occurred?

NOTE: I want to get some of the usual strawman arguments out of the way.

1) No this doesn't mean men would get a say over abortion. This would just be about their legal ability to choose on their own to not be a parent, regardless of what the woman chooses for herself.

2) If you're going to go into how men should just want to take responsibility because they chose to have sex and other pro-life arguments, I'm going to ignore it, the same way you ignore pro-lifers who give women these same moral grandstanding lectures.

3) If you're going to say it's not fair a woman who wants to opt out still needs to abort or go through pregnancy before they can surrender the child to adoption agencies, I'll say that's fair. So perhaps men can can pay for the abortion procedure or hospital bill, but beyond that is the result of the woman's choice and shouldn't involve him any further if he wants to opt out of parenthood.

The entire focus here is the idea that consent to sex is not consent to be a parent, so his legal responsibilities towards the child should not be entirely dependent on his decision to have sex if you believe in that pro-choice statement.
