I've been using these for about 4 years now. The comments going back and forth messy not messy is because they become messy when they overflow. When a tampon gets to full u see it on ure underwear automatically, but with these u dont realize it til u get and take it out and if ure not used to using them of course ure gonna think this is just how it is.as long as u change them in time its not messy. But unless u just went waaaay overtime the great thing is if they do overflow its not gonna get on ure clothes. I believe my period goes by faster with these...but I could be wrong. My husband and I have never had sex with these ...just can't bring myself to...but I could see how its possible. I've even been in a situation where I've literally rinsed it out and put it back in because I had no other option but u def cant do that with a tampon. Personally I love them. If messiness is the worry...until u get used to it, check it often so u'll never go to long.
