10inchadvantage, I understand what you are saying
I can get the erection up with a bit of help from my hand and then focus or meditate on the sensations of arousal while basically edging and massaging the base when I get to about a 7 or 8. This really swells up the erection especially the head. I do this for about 30 min to 45 min, bringing myself close to orgasm about 10 times, then zip up.
I haven't made through the day without breaking down and letting one buck.
Maintaing the arousal achieved from ballooning sure feels like it's doing something benificial with the hormones involved down there, but once I ejaculate I lose the feeling.
I sure takes discipline.
