help! choosing between the CB6000 and CB6000s sizes

Greetings everyone, this is my debut post and my spouse and I have just chosen to purchase our inaugural device. I’ve scoured the forum threads but haven’t stumbled upon a thread that truly addresses this particular dilemma. The CB6000 lineup appeals to me greatly. I need some guidance; when flaccid, I measure around 3.25 inches. The fitting guide on suggests the CB6000s for those at or below 3.0 inches, while the standard CB6000 fits those at or above 3.5 inches. Being right in that gap leaves me undecided. I lean towards the CB6000s because I believe they are easier to hide and restrict erections more effectively, yet my concern is spending roughly $150 on a cage that might be too tight for me. Your advice would be appreciated, and if this question has already been resolved elsewhere, please excuse the duplicate post. Kind regards, -HusbandObeysWife
