If the op of the other post saw my answer he'd conclude that I am an addict, personally I just think I am a pervert with an insanely high sex drive.
Anyway the answer to this varies and is dictated by my other half. When he stays with me my porn. Vewing (95%LP) is limited to about 7 hours per week max. When he travels abroad on business which is about 1 week in 3 then this shoots up to about 20-25. I usually watch two scenes an evening but a weekend this can be lots more. I must caveat the high peaks are because a) I may have made no arrangements to see girlfriends that weekend or b) it's lousy weather and I just fancy a chilled weekend in front of the laptop winding down with some porn. It's an amazing release.
It's also very seasonal and in the summer it drops off significantly as I am out and about more.
Being totally honest circa 2009-2010 I was single and really immersed myself in porn and I will honesty admit it got roo much. Some of this was me trying to understand my own sexualiity after a tumultuous couple of years where I convinced myself I was a 100% lesbian and that masturbating to women would be the solution to all my problems
Things got a little dark.
Now it's all happiness and bright lights and I have learned to use porn as something that co-exists with sex and not something to substitute it. I am happy
(and honest) xx
