I think bondage is not a freakish thing. I think it is a kink idea to spice up the relationship. You can go hard core or you can do soft play. So anything that isn't missionary is considered freakish or so said in the prudish world. So to spice up your life with yourself, significant other or friends is good. I just wish people would stop say freaks.
If you have a fetish or kink expand on it for yourself and others who are like minded.
As for me I have done many things and seen and experienced many different forms of kinks and fetishes. I have enjoyed and have been scarred. So all in all, a learning experience.
