I still haven't done any Internet dating or had any on-line relationships. But Internet still changed me drastically in that there suddenly came information allowing me to stop being a moronic bastard idiot Master. The kind of Master I warn subs about here. If the library has existed a wee bit earlier the world would have a few much happier subs in the world.
I've always had a knack for finding subbies anywhere. A picked up quite a masochistic beast at a buss stop once. My first wife. My slave now is my first slave I've found through the BDSM community. Which is a truth with modification. It's a tad more complicated since she was officially out of it when we met.
I couldn't imagine a world without Internet any longer. It's not just being connected but reading about anything at any age. Where the only limit is what you are curious about. I fucking hate people trying to save their children from information.
Reading what some people are writing here I suggest moving away from the Bible belt. Beside probably being spiritually corrupting, it's not good for sex. Sex is important. Especially pre-marital. It's easy to bring up the subject of BDSM here. Everybody knows about it and everybody no matter what age have thought about if and what they like about it.
