I have a question for the porn opt-outs, is it the porn or is it the masturbation? I simply dont maturbate to porn (and at all frankly), and have no problems with EQ or time in bed, I can really go an hour long rock hard. Typical sex is about half hour, but usually due to time restraints and my wife, she cant get the big O if there's too much sex involved, she'll start going numb.
as for porn habit, I'll occasionally watch to get hard, but not actually masturbate. Seems like if I'm hard for a good bit, then have sex later, I tend to perform better and it feels better (anticipation effect?)
