Example: Let’s say that a girl is changing her clothes and she has her bra and panties. And then, a guy goes in without knocking the door. Then, when she sees him, she get embarrassed and cover her panties and bra. But when a girl is in the beach, with smaller bikini with thong than the underwear she was using, she doesn’t get embarrassed. Why it is that? What is the difference that girls feel when they’re using an underwear and a bikini?
P.S. I’m not trying to say that girls should be seen in underwears without they getting embarrassed.
