I feel strange about masturbation...?

I was in Catholic school for 13 years of my life and regularly attend Sunday m, stemming from my Irish roots my family is very religious. I was told by instructors in my religion cles in school that masturbating is a sin because it is misuse of ual activity and becuase it is unnatural. Yet I soon found that this was kind of foolish becuase in order for something to be a sin it has to hurt someone -who does masturbation hurt - the answer is no one. It is actually healthy becuase it allows you to explore your ual identity in a personal way so that you can discover what arouses you. This is very useful when you are in a committed relationship. Science has even proven that masturbation can improve physical health by relieving stress and one of the most notable examples is that masturbation in men can actually decrease the chances of prostate cancer and there are health benefits for women as well - in the middle ages masturbation was used as a regular routine by doctors to help relieve PMS symptoms in women. I can understand your apprehension becuase I felt the same way but trust me you are hurting no one and helping yourself. Plus it feels good!
