Is this normal?

Over 20 days without porn.  I'm finding myself aroused and having pretty decent erections. I even started to get one today for no reason.  Which hasn't happened since I was in middle school. I haven't been able to stop masturbating entirely, but it's been something I've allowed myself weekly.  The first attempt to MO without porn was pretty bad.  Mostly limp and lifeless.  I was dependent upon porn for years.  The last couple times of MO I was able to get myself hard from just the touch of my hand.  Is this abnormal?  Am I recovering more quickly than others?  Others talk about taking so long to recover and flatlining.  Do you think I'll experience it later on?  I haven't experienced that at all.  If I'm having results this quick, I can't wait to see what will happen in another week or two.

Any advice, suggestions, etc... highly appreciated. 

Hello.

Regardless, the best thing to do is stop PMO for a period of time.
