My opinion is that if it takes 2 people to create life and it takes 2 people to mutually decide to have unprotected sex then 2 people should decide what happens afterwards. 

Yes it's the woman's body and she has to go through carrying the child and the pains of labor, but as a woman, I feel the man should get a say so in the after affects of sex.  Woman doesn't want the baby, but the man does then fine after she gives birth she signs her parental rights away and gives him the child.

Woman wants to keep the child but the man doesn't, then he to signs parental rights away and she raises the child.

It's not always the man's fault for unprotected sex.  No one forced the woman to spread her legs for a cock with no condom.
