Welcome to the circus. Don't let the clowns bother you.
The best way to get started is to look around the site and see what interests you. Even the stories and cartoons can be teachable for a newbie. And it might be best to start that way rather than jumping into the deep end of things with a marathon porn watching session.
In fact, in years gone by that's how most of us got started, with imagination fueled by stories and magazine cartoons. (That's a clue that I started long ago, well before the internet and video tapes.)
Then consider what you want and what's available. A family dog, even one that's fixed or a female can still open eyes to the feeling of an enthusiastic K-9 partner using an eager tongue on you. That will build desire for a dog that can go further and you can find information and help in taking the next step here.
Good luck in your journey and enjoy!
