I agree that they are extremely comfortable.
I think the first time I tried panties was in middle school. Parents caught me and told me how wrong they thought it was. Didn't revisit it for a long time. Into my adult years gf had left a thong somewhere in my possession. I wore it for her, and we laughed and still had fun. Kind of thought she was into it. Well at some point decided to order panty bundles from amazon, like a random assortment of 20 for $30. Did that a few times all keeping it hidden. (probably due to shame)
Well, I was working and she was looking for a pic on my phone to send her mom. She found butts and women's underwear. She thought I was cheating. She found out 3 hours before I was able to talk to her about it. I was like oh no I would never cheat on you! Those pictures are uhm...me. my stupid phone had 2 spots for pictures: gallery, and photos. She also was confused at the amount of them I had and in all sorts of colors and a few different styles. I hope with time, her and I can work through it. She did mention, "you know they sell guy thongs, right?" Ended up getting them quite a few years ago (ikingsky on amazon) pretty comfortable and they do have other styles. I still have quite a few women's pairs, but I put away the more "feminine colors" thinking that would help smooth things over. I'm pretty sure that she is just upset that I didn't trust her with my secret and always says how maybe if she would have found out in a different way she would have been into it. Dang it!
I honestly can't wear men's boxer briefs anymore. Literally zero support. tried to wear them to the ER one time and had to have a thong underneath for support. That was an uncomfortable day, but it didn't seem to faze the urologist at all.
This has actually been really nice being able to get things off my chest! I'm glad there are others who share some of my experiences. Life's wild!
