I have a kegelmaster too. Several years ago, I started to do some kegel exercises on my own and my orgasms were more intense, but I stopped due to well, laziness.
Two years ago I got the kegelmaster but I don't use daily. I have tried but end up forgetting. Last month I used it for a week straight and not only the kegelmaster became easier to insert, but my vaginal muscles became stronger quickly, and I could push that thing out without any help from my hands.
To the ones thinking "I am already tight, I don't need kegelmaster" - you are right, you don't, but it is great to work on your vaginal muscles, so sex will feel even better, orgasms will be intensified and you can squeeze that d!ck when it is inside you. Being tight has nothing to do with strong vaginal muscles, and that's what doing kegels is about.
I don't like using soap around or inside my vagina, not even that something Eve that sells at the store, except when I need to wash off when I am on my period. Never had any complaints about smell or taste
I noticed after taking several tablespoons of apple cider vinegar in one day that my p*ssy smell was stronger, but not bad, just deliciously intensified
