Well to be honest. It's not about size (always ), it's more the sensation and feel, the shape and scenario. But as time progresses, I guess you get bigger and bigger and the challenge changes. So just enjoy what you are doing, and don't worry about size and more shat it makes you feel when you play
Really 11.5 cm it's crazy I still have work to do the sensation must be incredible I started wearing plugs every day for three months and I see the difference I went from 5.5 to 7.5 cm and what's more the sensation is great in any case I thank you for answering me and if you have any advice I'm all ears π
