I did the newbie routine for the first time a few days ago, and I didn’t have the time to do it since then, but last night my girlfriend noticed that I got bigger. I measured myself again and I’m 5.1 Inches.. I guess I measured myself wrong the first time? Because last time it said 3.75”
But, my girlfriend knows my cock like the back of her hand, and she thinks I grew + she doesn’t know about me doing this..
Are noticeable gains possible after the first time?
