What kinda undies do u buy n wear?  Boxer cut,  bikini cut,  thongs,  boxers,  etc?   Personally,  I like bikini cut type.  The right amount of coverage n support for your crown jewels, more comfortable compared to thongs which has the cloth string behind which tends to slide up your butt crack which is kinda uncomfy at times, and is also sexy due to the shape (with thinner at the sides) which doesn't have too much cloth, ie.  just the right amount of cloth where it is needed.
