Teaching boyfriend to use tampons? TMI

Other day I was putting in a tampon naturally he wouldn't get out of the bathroom usually never does so he watched me put a tampon in and he was very confused thinking that the whole entire thing went in. So I explained to him you know what actually goes in then showed him what happens when you push the thing in at the bottom. Then today he put a tampon in for me so he could know how to do it and he said "I don't think it's in all the way there's a blue thing hanging out" me:"does it look braided" "yes" "that's to catch any leakage " "oh that's weird" (trust me he asked to know how to do all this stuff so I showed him)
