Is it normal to wear a tyrannosaurus costume during foreplay?

After much begging and pleading, my wife has finally come around and now allows me to wear a T-Rex costume during foreplay. I just can't imagine getting my freak on any other way; normally, I would have to simply imagine that I am a dinosaur in order for this to be the case, but now that I've come so close to making my fantasies a reality, I just can't go back. The thought of women being forcefully taken by some sort of monster has been a longtime fantasy of mine (I blame the various examples of such phenomena in the media for corrupting me as a child), I suppose because of how brutish and animalistic the whole concept is. Of course, I now have to compromise and engage in more of my wife's weird fantasies, but in spite of everything, I think it's all worth it. We're not hurting anyone or anything.
