took me a sec to parse that till it clicked, and yes i am about to over analyze the horny XD
But imo, orange is about all you need for prolonged/ directed stimulation, especially so with the second one working the back XD getting to blue/ purple is more a factor of your biology id think, cause not everyone is "deep" enough eh? now, something to work on for the back side? id fully support that kind of training XD
(based on most common results of sizes for ones that most closely match the description, toys appearing identical from same brand and etc seem to be labeled as 7", 8", or 9" on different sites depending on how they chose to measure it via total vs "usable" length, either way each color loosely equates to 1.5" with give and take on both ends)
ofc this lead down a rabbit hole as one might expect
Happy Toysday! XD
