It doesn’t hurt going in like tampons do. It’s a little weird going in but once it’s in place you DONT feel it. It’s a great product and while it takes about a few days to figure it out, once you do you never wanna go back to pads and tampons ever again. I’ve tried them all, pads, tampons, cups, and period underwear. Flex plant+ disc is the best product for people with periods by people with periods. Guys, gals, and un binary pals, this is for you!!!
