In theory, it's all very well to use the elastic band trick.

2 potential probs though. If you fall asleep with it on - Gangrene (OUCH - and worse!!). Plus, having to stammer and blush through your explanation if/when someone says "Excuse me, but why do you have a rubber band around your cock?".

I know that if using a little blue pill, I can maintain a semi for a day or two afterwards, so maybe a quarter or 8th of a tab in the morning might work (could get addictive, tho, or pose other health risks). I might try that one and report back the results.
