Consider how adolescent boys relate to sex. The baseball analogy of first base, second base, etc. is almost universal, because to boys, sex is a goal oriented pursuit.
Adolescent boys hear the (mostly bullshit) stories of their peers, and their own sexual "achievements" probably don't measure up to the bullshit. Sex becomes more about how far they can get a girl to go than anything else, and figuring out how to get their hand down her pants or up her blouse without being rejected becomes WAY more important than considering if she enjoys it. If a boy cant achieve his goal, he thinks there must be something wrong with him, and if he can, the boost in self-esteem and confidence is added to the sexual gratification.
Fast forward 20 years, and the process is ingrained, but it's no surprise that second base just doesn't cut it any more. Anal, facials, bondage, water sports, video, threesomes, ATM, bareback, etc. are the new second base.
The internet, and the exponential increase in the number of women doing porn has convinced me that I'm the only guy in the western hemisphere that can't get a woman to try a "dirty pirate", but I'm not giving up!!! Being goal oriented is a good thing, right?
In order to stop these sick disgusting things from happening to women, we must start at the beginning, by making sure all adolescent boys get laid on a regular basis. Moms, take an interest in your daughter's future, by getting to know the guys in the chess club!
Or
Just accept that guys are naturally perverted, and use that knowledge to pay your rent.
