How To Avoid The Trap of A Slippery Kitty

We currently live in a Men vs Women type of society. Baby trapping is one of the biggest pitfalls a man could fall for in life. This is no secret, yet men continue to fall for it. Why is that? I can't understand how men continue to get suckered into it. With STDs and STI's, you'd think that condoms would be required equipment amongst men. I'm not talking about paternity fraud, I'm talking about guys rolling the dice on vagina. Why are men trusting women on birth control if you don't want a child with her? Why would you want a child with a woman who you don't even want as a wife? This is some food for thought that continues to perplex me.
