Well, I dont have a straight yet (Mostly just lurking here to learn about them until that glorious day that I actually have some cash and can afford one), but I've been shaving with a DE for a few months.
A big reason is the fact that it irritates my face less (Or not at all, usually). I have sensitive skin and tough hair, so cartridge razors tear my face up.
It's also more enjoyable to shave. It's actually nice and relaxing to take my time lathering up with a brush, and quite satisfying to get a good shave the "old fashioned way".
Also, it's pretty rare to find someone that doesn't shave with an electric or cartridge razor these days (Well, they're plentiful on the forums, but I've *never* met anyone in real life that uses anything else), so it's kind of nice to stand out from the crowd.
Hooray first post
