Am I sick because I am into ?

You are definately not sick! I can't beleive that you think you are! You've just got to find the right person and make sure you chat about what you both like before you actually act on it, or the first time you try what you want to go slow and keep asking if she likes it, It's not sick, personally I'm really in to and both domination and submission (depends how i feel and what I'm wearing lol) and i don't think it's weird at all, everyone's into to different things and you can't change what does it for you've just got to find some people that are interested in trying what you want to try then let your imagination run wild and have fun, but if you've got anything in mind definately have a safe word!
