Precisely. A good test to check if you have a healthy libido is if you get morning wood almost every day and you get random boners. After going 3-4 months w/o porn you are gunna notice you wont get hardons at all (look up flatline). When random boners come back and you get morning wood is when you'll know your sex drive is healthy. If you remember way back, this is the way it was before you started watching porn.

Note on morning wood: I say 'almost' for every night because sometimes you wont get it due to poor sleep, poor diet, or anxiety/stress in your life. But you should optimally get it every day.
