I used to wonder too. I fell upon this" Hobby" as a last resort in a time of need...At first I did not enjoy it, but the thrill and the people I have met along my awesome journey made it not just worth it, but glad I was dealt this hand in life.
Not only did I find a solution to a problem I had in life, I also found a world where I could relate to other people with a odd sexual appetite like my own , I love it! I don't feel like a weirdo anymore....lol
