I really must be misunderstanding this discussion but it sounds as if the OP has fastened his crotch strap first, is trying to step into the strap, and then insert his arms in the harness. This would be somewhat akin to trying to jump into a pair of pants, both legs at one time, while holding them by the belt. I will go back and re-read, maybe after a cocktail it will make more sense.
you are right... that is absolutely what I did
