i kinda feel like girls in the store were looking at me constantly while I looked at thongs and boy shorts and showed them to my date
Most Helpful Girl
Sigh, the customers were definitely staring. Not everyone is comfortable shopping for their skivvies in front of strangers to begin with. They find some level of comfort in the notion that at least they're "safe" because they're surrounded by women -- especially if they're buying a body-enhancing item.
So if you are there with your girl, don't scope the other women there. It's usually a private moment for them. Try to resist the urge to dive into the bins...
If your girl takes you there on purpose, during a date, it doesn't take too much sleuthing to figure out that she wants (1) you to be thinking about what's under her jeans/etc.; and (2) to know what you like in that department so she can pick out something you'll like to look at.
