Well as far as I'm aware females haven't figured out how to reproduce naturally without a guy. So if they keep showing up pregnant there are two people involved. If all the guys out there would start using a condom there would be a lot less children running around.

Oh but you don't want to use a condom. No you'd rather the female be on birth control (which can have health consequences for the female). Then you shame the female for a night of bad decisions (on both sides) if they choose to not carry your child. Then you shame them even more if they have the child because they now have to deal with being a single parent. Oh but then if they refuse to have casual sex there is something wrong with them or they are cold or they must already have 10 partners and just don't want you.

You can't trust a female to be on birth control. Its expensive, some insurances still will not cover it. The long term methods that a lot of insurances will cover can have side effects. How would you like a piece of plastic stuck inside of you that could migrate and end up piercing your insides? Does that sound like fun? All so some guy can treat you like a cum dumpster?

So guys take some small amount of responsibility. If you don't like condoms fine go find a flesh light and save everyone a lot of trouble.
