I used to on a daily basis, maybe 1/2 to 1 hour every day or two since teenager years. About 5 years ago at age 30 I decided to cut down and now I rarely look at porn, maybe see some pics on getbig by accident here and there.
A few months ago a relatively attractive married woman at work gave me her phone number out of the blue, and I got an instant boner in my pants. That level of arousal would have never happened during the porn days. This was at age 35 with no steroids in my system, strong libido, ready to go at any time. Porn is a libido killer and many people don't realize it.
Then we stuff have this:
Porn totally f*cks up your dopamine system. I actually had withdrawal symptomes, such as mood swings and lethargy, when I quit. People don't realize how it affects your mood.
I decided to quit watching porn not for sexual benefits but for mental ones. My concentration is much better since i started my reboot.
