Watching porn too often or everyday can and will lower your vibration.
Because watching two people get it on that do not love or honor each other sends messages to your body & brain that it is ok. Porn often depicts the males getting pleasured and the women being submissive and faking their enjoyment. This is not sacred. You will enforce those lower beliefs within you that say sex is meant to be that way - detached, painful, fake, lustful, degrading, and meaningless.
If you want to higher your vibration and heal your sexuality, turn off the porn and focus more on lovemaking that has love, integrity and care.
