From the day you notice your breast buds through full development breast tissue density is going to change.

I'm still growing, so I'm also assuming that my breast tissue will likely be firm up until the growth stops. Is that an incorrect assumption?

When I do a BSE (Breast Self Exam) It's easy to tell that there is some much denser tissue in there. Slightly bigger than a mini-doughnut and a bit firmer.

Is this similar to what your growth experience has been?

Spoked, you can check (self exam) anytime, in the shower, during a massage, visual changes, etc. Genetic Male breast growth tends to be fibrous (knots), I get them too. When they're not painful is the cause for concern, I usually try to loosen them up with massage. You could try cold water therapy, and drink plenty of ice cold water regardless, it's good for boob health. Actual tissue growth can differ upon individuals, one type is loose tissue, aka as psuedo-gyno (fat and squishy, lol). Great question, a perfect time to say: KNOW YOUR BOOBIES-
