U By Kotex

So, my first tampon was a Kotex click light and it hurt so bad! I have used others since but I am wondering if anyone else has the same issue with u by Kotex products, even the pads are too small for me. The only time I got relief from the pain was when I went into the pool. I’ve watched tons of videos on this and people swear by the click ones even my sister does, went to the store with my mom and she bought me playtex sport but swore by the u by Kotex pads which are too small for me and i leak out the back??
