Boxers or Breifs? (Patreon)

I often get too hung-up on referring to a specific type of underwear in audios (boxers vs. briefs). 

I don't want to take you out of the fantasy when you're listening. 

For example: If you're a boxer wearer and I say "slide your briefs off slowly baby" and vice versa.

I usually just say underwear  - as I did in my latest "Jack Off" audio. But I'm not sure that's any better. 

So my question today is.... 

What's your preference when I'm referring to your (a man's) underwear in audios?
