Girls, My Date started laughing after she saw my briefs. Should I keep wearing them or make a switch? Do you think she will tell her friends about it?

She said that she could not belive that anyone still wears white briefs (or tighty whities as she called them). I mean after that we kept going and had a great night. After that she said that i could keep wearing as i am in a good shape but i still think about switching as the situation was quite emberassing.
