1.) It makes you cunning and carnal.

It slowly corrupts you and turn you less humane. people like this talk about sex and dirty stuff all the time. Most of their conversation topics revolve around carnal pleasures. They are full of innuendos and have mostly such things in their minds. They hung around with like minded people and share their saucy experiences, their bf's penises, their gf's bj skills etc. They became judgmental. They look at people like meat and scan them as they enter a room. If you hang around such people they'll turn you like themselves.
2.) It makes you desensitized and makes your heart colder.

Your romantic, innocent, poetic, aloof self exists only one time. It will never come back. And it is meant for your one, lifetime partner. As long you exercise your egotistical will and get heartbroken, you become cynical, your heart cold and less acceptable of love, and you see the other gender with resentment and mistrust. Even as a mere sex object after a point. Thus the phenomenon today of male and female players.
3.) It is egotistical, irresponsible and unthoughtful of others.

An unborn child being aborted, your parents shocked and saddened, your teachers and mentors dissapointed. The other person being used for your selfish goals. All these people affected because its all about me, me ,me. It has the pretence and excuse of love, but it ain't true love. Cause true love is humble, it surrenders its will, and it never hurts others.
4.) It doesn't blend well with spiritual practices. (Nor does masturbation)

Well don't take my word for it. Try it on your own. And i dont speak new age demonic pseudospirituality bs, but real spiritual practice like contemplative prayer.
