How so?
At one time, all it took to get off was the bra section of the department store catalog.
Then to get off, it required dedicated magazines such as Playboy, Penthouse, Hustler, etc.
Then to get off, it required XXX in video format which we could rent and take home.
Then to get off, it required XXX specialty cable/satellite channels so we didn't have to leave home
Then to get off, it required the Internet, to access all the XXX pictures and videos we wanted, for free.
Fast forward to today, where we can now access all the high-quality, hard-core pornography we want, at our fingertips, at lightening speed, 24/7/365, through countless sources, in countless formats, all via many media devices including PC's, Tablets, mobile phones, etc. And with recent advancements in virtual reality, porn will have another medium, which some experts say will be the considered the norm in terms of how pornography will be viewed in the very near future in ones own home. Meanwhile, the everyday, living, breathing, average female you pass on the street, becomes less and less appealing to your senses. And it only gets worse.
