I have one and I don't see it as trashy, and I don't think anyone else thinks mine is trashy either :') No one really sees mine but I just like having it, I only really went to the beach once last summer and it was kinda nice to have then I guess.
At the end of the day - it's your body and your life and don't get it if you don't want it. Plenty of girls have them and lots of them aren't trashy :P
