QB, I’ve always been a stealth PEer, which is part of why the AFB hanger can be made out of inconspicuous materials. I went to considerable lengths to conceal my original hanging PE from my wife, because I was so insanely excited about what I could see happening (sounds like you might relate to that ;-) and didn’t want her opinion or ‘you’re fine the way you are’ shit. All worth it when one night in bed she said ‘wow you’re huuuge’ in a way that made it clear that what came next was going to be good.
A few observations:
Warming up: the only time I have EVER done a warm up is thinking I *should* after reading about it here. Goes against local groupthink, but consider: as soon as you start working your penis with your hand, you’ve got more warm blood circulating through it - so what’s with the cup of water?
Lube: I have used lube, but not in a long time. Partly a stealth thing, but you can certainly get a good grip and work different areas without any lube at all. I’m circumcised, but through trying to restore foreskin I have enough that I can work almost the whole shaft without friction. Save the lube for pleasure?
So: If you don’t need to get wet and greasy, why do you need the bathroom at all? You can do all kinds of stretching in bed while your little brother snores (or with someone snoring inches from you in the same bed, for that matter). Unless you need to jack off every time, why not do a few minutes whenever privacy allows? I do my current 5-minute exercise (in futility? Ya veremos) standing, fully clothed.
And one more…
Education: a good thing, but don’t confuse college with education. If you want an education, read. Travel. Watch lectures and documentaries on the intertubes. Take specific courses at your local community college to learn skills that will serve you well in the post-“We're Amurka and we're number 1!” happy face government-handout consumer binge world. (FWIW, I am not anti-America; it’s just that the America I loved no longer exists in the United States…not to get too far off subject….) As you’ve experienced, the most wretched colleges exist as indoctrination centers - something that can also be said of the Ivy League university I attended - while the better ones are still a total waste of time - or opportunity: how much more could one be learning through travel! - for the vast majority of their students, many of whom leave with an impossible debt and diploma that might - or just might not - help them land a job flipping burgers or working in the deli of a supermarket.
