I should probably wash mine more than I do.  I have three underworks double fronts that I wear, two primaries with one backup just in case.  Every couple days, or whenever I feel like it, I swap out.  I wash them when they start to smell or get dirty.  I put them in the dryer on delicate for about 15 minutes then hang them up to air dry.  If I need to freshen one up quickly, I'll stick it in the dryer on delicate with a dryer sheet for 5-10 minutes.  They've held up pretty well.

Hey, nothing says 'guy' quite like 'I smell like ->-bleeped-<-, and I don't care.'

I'm not very physically active, and I'm also a bit lazy/don't really care so much about the smell, so...

I wash mine... Uh, wait...  I can't remember the last time I washed it!  I'm pretty sure I got it in December, and washed it once in Dec also, so that would mean that my current rate of washing is... once a month.
