Unfortunately, switching over to panties in one fell-swoop is not feasible for most sissies. Male underwear is an addiction you have to break, girl. And just like smoking, going cold turkey usually ends with poor results. Some sissies have a fear that people will notice, some start too lavishly and can't find panties to wear every day (ironically named boyshorts are perfect if your clitty is being bothersome!). And some sissies have to contend with snooping roommates and family members—so it can be important to go slow.
Needless to say, if you don't even have any girly underwear, your first step is going to have to be buying panties (I recommend using packs of underwear to help build your wardrobe at first).
Now gather up all your inappropriate male underwear. How many pairs do you have sissy? That's how many weeks you'll be working on your assignment. Grab a permanent marker or a scissors. It's time for your weekly ritual. And remember: never touch yourself before you complete your assignment.
Start by repeating this:
Good girl! Repeat as many times as necessary.

If you carefully handle your clothes and have a suitable dainty lifestyle (or you're on your second week), you may find that all of your bland male underwear is in tip-top shape (at least in terms of fabric quality). In that case, take your most stained, dirtiest or frayed underwear and get rid of it the same way as before.
Once your old male underwear is tattered remnants or properly marked, throw it in the trash where it belongs.
This will be your weekly endeavor. Set aside a day each week and do it like a good girl. You will slowly wean yourself off the unnecessary habit of wearing men's underwear. As a bonus: more room for awesome girly panties or other clothes in your wardrobe.
(For secretive sissies: other people, like family members or a wife are still allowed to buy underwear for you. You are not allowed to ask them to do it. And you're still going to have to do all the weeks you set forth at the start.)
