How come i enjoy masturbating so much?

Because it's fun: Only an ideologue will tell you that it's unspiritual or will make you care less about other people. If erotica becomes an obsession that's obviously interfering with the rest of your life, get help from your physician. It prepares your mind and body for adult life, keeps you able to focus, and is one of the few things that's really enjoyable that won't harm you.
