Use the search button - it’s a common question.
I almost always just spray everything on my neck in different areas - front, back, sides, behind ears, below chin, chin/partial face. 
I also heard of other spaying heavy NONE like TUTH near their dick but I would think you should already have the girl alone and your pants off first
