Billy, welcome on boat ! hehe...i think that we all started like you....we bought a few thongs at first, wore them a few times a month, then more days during the week and so on....i think also that everybody in this forum are very proud from your evolution ! I agree totally with Thong24.....if you dont want to get rid of the other underwear you have....you can do this : keep only 1-3 "old" type of underwear and put them deep inside your underwear drawer.instead put the thongs in front and from now on buy only thongs....soon you will have a big collection of thongs, at least you must have one for every day and some as backup if you need to change during the day....
after some time move the old type of underwear away from your drawer, maybe put them high in your wardrobe so it would be difficult to reach them--so you are going to use them only in emergency situations---
believe me Billy, like thong24 already said, if you do this, the feeling that you have to wear thong as a only option is something sooo beautifull, beyond any imagination!!
