"It really isn’t a straw man. Clearly the father couldn’t keep parental rights and not pay, but if he gave them up it is very similar."
No, it really is the definition of strawman, which is, "refuting an argument different from the one actually under discussion, while not recognizing or acknowledging the distinction."
"This is a straw man, though. Religion is completely different! I am talking about non religious people who would accept their partner saying no PIV sex because I don’t want a baby? How many would stay in the relationship if a guy said that (or a woman)? I don’t think many (any?) would just consider it a mature and considered decision and accept it."
You didn't say that, though, did you? Again, one more time, "It is totally vacuous as it is not a real world choice. Do you know of a single woman or a single man who has ever made this choice in a relationship? If not, it is just a silly hypothetical."
Abstaining IS a real world choice. I do know people who have abstained, so I know it is not a silly hypothetical (as an aside - how patronising). I can only answer your arguments as you frame them. It is not my fault you do not know how to frame them. So not a strawman as I answered your argument.
Would I be happy to abstain? No. I wouldn't enter into a relationship with someone who wanted to abstain either, but I think it is a valid choice. I also accept that any resulting pregnancy from a relationship that involves PIV will be my responsibility to deal with. But then, as a women, I have to, as it is my body it is happening in. We don't have get out clauses.
What I find 'silly' about your argument is that is completely unreasonable to expect someone (men) to go without PIV sex in a relationship, but not completely unreasonable to have circumstances where they do not support a resulting child.
