LOL rest assured you are not a freak, I am sorry to say though it is not a fetish of mine, but I do do it for him.
I'm wondering though with this statement, is it the actual gagging that turns you on, or is it the fact that you are giving someone else that pleasure that turns you on more?
I know that I do it because he likes it, he encourages it. The initial act for me is something I could live without, but I do it and I like doing it only because he enjoys it and his enjoyment is what motivates me and turns me on more.
