I don't have any credible resources to link to other than facts about the refractory period. You will just have to take my word for it or actually attempt such a thing yourself.
I did use porn but I have never ever felt like choosing porn over a real life women. Its just never been a problem to me, when i watch porn i usually imagine that the guys dick is mine and try to picture what the chicks cunt or ass would feel like.
I seen results within the first day, and as for lube Iam not circumcised and i've been jacking off since i was about 10 I have not been bothered with cuts or abrasions from jacking it too much since i was about 12 and that only happened like once when i tried dry humping pillows.
