Been into BDSM for years:)
I've liked it for years and years, any aspect of submission and control :) But at the same time I hate any form of abuse, and it doesn't make me or anyone that likes it 'abnormal'. It's healthy :)
I know a friend who does some form of it and I do some light things with my wife and our mutual lovers. There is nothing wrong with it indeed! My wife and girlfriend love the feeling of being controlled, secure, and safe in my arms and to act on what others might think of as uncouth fantasies. In return it makes me feel powerful, charismatic and godly which is something that's unusual for me because I struggle with self-esteem issues and whatnot. Even if we don't practice what might be considered "true" BDSM to the community as a whole I can understand the mindset and appeal to it.
