Oh I agree. It's not fair to put the onus of sex=pregnancy solely on men. Women have a desire for sex just as men do and both bear the responsibility of handling birth control. But men suffer from two issues regarding that.
Firstly, many guys just hate using condoms. It affects the sensation of sex and it adds a step to the whole process of getting down to the deed. If a girl tells them she's on the pill and they can bareback her, very very few men will even stop to consider the consequences. Secondly, its just easier to let the girl handle it cause all she has to do is pop a pill right? Men rarely, if ever, stop to think about how often she has to take that pill. Nearly every day of each month. Without failure. Never forgetting to take that pill on the proper day. And if she does? Or if she's really stupid and thinks she can trap a guy in a relationship by getting knocked up? Yea, that stuff usually gets discussed after the shit hits the fan and he's cryin' the blues to his buddies about child support.
Men have to make the conscious decision to take back their power to decide what happens in their lives when it comes to sex. For now, if you can't stand condoms, get a vasectomy and you can pump and dump all you want without fear of unexpected pregnancies. If you don't wanna do that then use a condom even if she's on the pill because it's just an added layer of protection for you AND her. Men have to at least make an effort towards preventing pregnancy if they want to have a right to bitch about about it if it somehow does occur. Leaving the decision making entirely up to women to handle birth control is essentially giving up your right to complain about it.
Now I know there are some guys out there who ARE smart enough to protect themselves, and yes its possible for condoms to fail, and yes its possible for a girl to lie about being on birth control, but at the very least MAKE THE EFFORT to protect yourself. If nothing else you'll reduce the chance of an "accident" happening, and if you want guaranteed baby-proofing, go for the vasectomy and be free to go condom-less without worrying about pregnancy at all. My buddy never regretted his vasectomy. He said it was the smartest decision he ever made. In fact he says it adds an extra psychological layer of pleasure to sex just knowing he can drop a load in any girl at any time and never worry about a kid popping out. His freedom is guaranteed.
