Testosterone Booster?

I mentioned before that one of my favorite FWB FBs I got with the first time when he had just turned 21. His cock may have been 5.5 at most and it was on the thin side. It did leave me yearning for just a little more but his hotness factor made up for any shortcomings he had. I noticed that he also began to lengthen and thicken just a bit. Now he is 30 and I measured him again and he is an even six and has a girth to him that he didn't have at 21. Not a lot more but it is definitely noticeable (sensations!). I have read that this lengthening and thickening can occur up to the age of 23. I would say that I don't think that your 5.75 is at all small. I would say you are average. I too would try other things and probably jelqing as well.
 
Jelq, pump, cock ring, eat well, clamping, routine, rest days. until you get to size women struggie with then stop. Then pump 3 times a week and help maintain size and cock health get your partner to help good times promise.
 
well, you are at the average size. your dick can and will grow with patience if you follow the PE routines on this forum, i jelq 100x then pump for 5 minutes, massage for one minute (jelq) and repeat that pump massage combo for 20-30 minutes depending, then i masturbate and kegal as much as possible, i do that 4-5 times a week, trying to rest in-between. you will get bigger if consistent you will begin to notice gains after 6 months.
