I Love Wearing Female Underwear

I actually don't get how some guys do this? Long story short I was forced into it a while ago, all my underwear was either in the wash, "borrowed" by family or had been donated/recycled in my wardrobe clear out. I had to wear jeans for a formal occasion so i needed underwear, commando in jeans does not work, all that was in my drawer was a pair of my stepmums briefs i had worn for a dare and she told me to keep because she didn't want them back. So in my desperate state i wore them, and my god I've never had to readjust more in one day before it was so uncomfortable. Do the men who do it full time not have balls or something?
