Ahem— This is a gynecomastia forum, not a cross-dressers' forum. As one member has said to new ones coming in with gyne, "Welcome to the club nobody wanted to join." Nobody wants problems; but if breasts are coming, we might as well make peace with them and get comfortable, even enjoy them if possible (in some men's cases). Surgery is not an option for many.
It's common for one side to grow ahead of the other, and so far I only seem to have one breast. I can grab a small handful on the one side. The problems started a few years ago before I even realized it was growing. It's still small enough I can hide it ok (as long as my shirt doesn't fit very snugly), but there's a little nagging pain and irritation if I go without a bra or bralette. I work at home, and start the day without; but after a couple of hours, I've had enough, and I'm ready to go put one on. I do not start the day thinking, "Oh boy oh boy I get to put on a bra!" I procrastinate putting one on. Then it feels good. I originally started with a bralette that's marketed as a sports bra, at the recommendation of male marathon runners for remedying nipple fissures which I was getting while riding bike; but as the problem progressed, there was a time I was just milling around the house and I really felt like I needed something, so I put one of these on even though I wasn't going out for a ride. The relief was instant and amazing! Wow. This was still before I realized there was some growth happening.
Bras with small enough cups in my band size are rare. A bralette helps a lot, but there's still a little discomfort from the fact that these just squash the breast down. I have some really cheap ones that do better, having a slight cup, but they kind of bite into the lower fronts of my shoulders. I'm still experimenting with various brands, trying to find something more comfortable, easy to hide, with no lace, flowers, bows (unless I can cut them off), girly colors or patterns, show-off back, etc.. I have a couple more on order. I would like one with narrow wings and straps to minimize heat in the summer and minimize the binding and scrubbing when I twist sideways like I get with the wider ones. Hooks have their purpose but they can be kind of uncomfortable too, not to mention hard to hide, let alone pass the hug test. Ironically, it would be advantageous to grow a little more to fit the available cups, but I certainly hope I can stay pretty small there.
