An "S" does not always mean aggression, it can just be a comfortable position.
From the angle of the photo, it is hard to tell, but it looks like your snake is resting his head & neck on your hand. That seems relaxed to me. An aggressive (or fearful), ready to strike, type of S would be with the snake holding its head & neck up in the air in an S.
However, if wearing the gloves gives you confidence, there is nothing wrong with that.
