Move up a size with hydromax?

[Dannyjuice]

So I bought hydromax 7 , as I was about 6 5/8" bpel starting. Latley I'm passed the ruler on the hydromax by quite abit not touching the end tho. does anyone have any experience on being right on the cuff of two sizes, if I went up to the hydromax 9 would the extra eliminate water create way more pressure or is the 7 fine as long as I'm not touching the end. Want to keep growing so if it's a hindrance I'd spend the money to get a new one. Thoughts?

I'd say keep it until you reach the small dome end before the nipple release. Then upgrade to the bigger model where you have the hand pump to achieve higher pressure than just pressing it against your body.

Good call, I wish I got the hand pump in this one. Was the first device I bought. Some times it's a pain in the ass to get proper suction
