Will sparring against my instinct, hurt my instinct?

So today I sparred for the first time in my new cl. It was a kickboxing match with no head-shots. So basically only punching and kicking the body. Whenever I got close my instinct was to elbow or knee. Whenever I punched, my instinct was to aim for the head. I had to consciously fight that urge. So if I keep on fighting that urge, will it hurt my instinct because I won't want to do it anymore?
