I normally go commando except for very important occasions. I also find underwear to be restrictive now that it's been years since I've worn them on a regular basis. I've only dealt with one situation in which I got hard and couldn't control it...something about the subway vibrations got it going before I could stand up and avoid the sensations. Of course, it had to be on my way to work. I was panicking, but luckily my hands in my coat held up front seemed to disguise it until it softened to a semi. One thing to keep in mind is that your dick will expand to a larger degree if it has room. So what if a few people notice? Enjoy the feeling of your dick not being squished when you sit down, and how it sways when you're walking around. You'll spend a lot less time adjusting, which is an act itself that draws attention. Trust me, your apprehension regarding the situation is much greater than reality.
I only sleep nude and quite often wake up with a boner
