boyshorts are soooo comfy
"I appreciate this whole seduction thing you've got going on here, but let me give you a tip: I'm a sure thing." - Vivian Ward (Julia Roberts) in Pretty Women
Panties definitely. They give much more comfort and even pressure around your body. I hate thongs, they creep up your butt and chafe badly. Also when you pass wind, there is nothing to trap the odor.
Bikini or thongs dependant on my clothes and feelings.
The sexiest panties I can find, usually a thong or g-string
