Practical underwear recommendations for a small penis

Hi guys, there comes a time when most of us at some point have to wear underwear for whatever reason.
With not having much to support I'm interested to know what type of underwear people find the most comfortable and practical to wear for a small penis and why?
I'm also thinking about those times when you're wrestling to get your willy out quickly to have a pee, what style works best for you?
I know it's first world problems but still interested to hear any recommendations!!
