I have hundreds of thongs (mainly girls ones cos they turn me on more) currently I own love honeys thong:
This thong is the most supportive and comfortable one I've ever owned, the support gives me the confidence to wear during the day. No ball slip unlike some ladies underwear.
Bit of advice if (like me) ladies lingerie gets your motor running. Try and buy sports things, Lycra cotton examples or anything with some stretch up front, they will support the trouser snake well. It give you the tighter feeling and nicer materials lingerie has to offer.
And also just got these for dailywear. Cannot recommend enough, they're the best of both worlds if you don't want to be venturing out the house in you partners g-string:
I want these next though:
