I remember a topic about sexy or cute panties, I picked cute, and on that matter, well, plain panties gets me going but stripes are a plus, so stripes FTW!!!
If I have a preference, I'd say it would be for solid colored panties. That's not to say I don't understand the awesomeness of striped panties, but the style is somewhat negligible. I'd be a bit concerned about myself if I rejected a girl because I didn't like her panties.
What is the difference between Plain colored and Striped? It's count who is using it..duh.. if my Gf wears striped panties, then.. i'm turning on, on striped panties, and if she using plain colored panties, i turnin on too
