Maybe we should force all men that want to avoid being a father to have vasectomies since your approach basically makes all women that have boyfriends (partners) that are unwilling to be fathers get an abortion.
Simple solution for any man... If you are not ready to be a daddy then do not put your penis where it will create a child.
I would love to see you try to make the argument that if you got an STI from sleeping around that it is completely your partners fault that you failed to protect yourself. I am certain that they can not take the STI away from you.
