Well; I also have a tremendous straitjacket fetish, but only for leather and rubber or latex jackets, especially with attached hoods. My wife was hesitant to get to involved until I had a leather SJ made up for her and she found out how enjoyable it can be to be bound and brought to orgasm through 'mechanical' stimulation. Now we switch and play quite often, and we have been married for almost 40 years. Good luck,
Jack
