It is only an issue if it occupies a significant part of your time.If the rest is balanced it shouldn't matter and is no doubt because you are in a prime age range hormonally.Is it impeding on all areas of your life? In other words do you pursue friends,recreation,self care,other endeavors?I disagree with the previous poster,as you've not submitted enough info for anyone to assume that you are unhealthily indulging sexually pleasuring yourself.Things are an issue when they rob you of other aspects of necessary balance,activities,endeavors.Or when something seems to be ones only pursuit,and/or they feel compelled to do it and don't want to.
