OK, ya do know that not every item of clothing created for women is used to seduce guys. The thong and d-string were originally made popular cause they got rid of the VPL, Visible Panty Line. This is the when the edges of the underwear can be seen through tight, and sometimes not so tight, trousers and skirts and so forth. Its just when guys found out about them, wooooooosh!!!!!!!!!!! Off into sexual lala land they went! So, to answer your question in a more simple way to suit your needs, thongs have a function other than to give you a hard on, not all women show them off by wearing low cut jeans and the like. A surprisingly large amount of women wear them and you would never know cause they don't flaunt them.
