Try wearing a FedEx or MacDonald's uniform or even a nurse's dress. Read fashion rags for the latest trends. Take it off slowly, let them have it all during the slow jam. You should try reading erotic literature to learn the art of building someone up to the point of no return. Leave those horrible g-strings and underwear at home or in your sports car.
Underwear is a very erotic object for a lot of people.
Pick more sensual colors or something. If I see another skintight, red g-string that looks like a Speedo diving piece I'll yack. Just don't do the hippie Guatemala fabric, it's been overkilled. If you're not going to let your beard or stubble grow, then you may as well put on some dramatic face shading. Use your imagination.
