Hello everyone,
New Poster, but I've been reading the site for about a month and have caught up on all the past threads too.
I hope no one takes this the wrong way, but I really see a disconnect between feeling masculine and then being afraid to wear something (such as a bra, sport top, cami, whatever). In my mind, being a man (or being masculine) is about being your OWN man, and doing whatever the heck you feel like (save for perhaps felonies) no matter what some other person thinks about it. It seems girlish/feminine to care more about what other people are thinking about you or to have an extreme interest in gossip about you.
Make no apologies, explain to no one what you're doing if they're not sharing a bed with you.
Perhaps its my experience with having a slight disability. Learning at a young age not to give a care what other people thought. But its not masculine to lack self confidence. Whats the point of enduring pain, discomfort, or fear because someone else might notice your solution? When I read stuff like that, I think of those people I've seen with runners nipple (severely chaffed nipples) bleeding through their shirts. Yeah, cause that makes a hell of alot more sense than a sport top.. or perhaps its better to put duct tape on yourself a few times?
I know that some people here have some really big breasts. But for those of you with C cups or smaller, do you know there are guys out there that get some kind of thrill out of wearing bras out in public when they dont need to? They can have the same fear of being caught as you do (acceptance, job, whatever). There are whole websites out there describing how to hide a bra (and they are intentionally putting forms in to make themselves have boobs). I'm not saying everyone should be excited about the prospect, but I am saying that you dont always have to choose being public about it if you decide you will be more comfortable in a bra.
In the end, if someone says something about it, ask them right to their face if they have a problem with it. That'll shut up 90% of people right there. Please don't negatively affect your life through pain, discomfort or shame.
In a slightly different angle of looking at it, seriously, you're not the center of the universe. What may seem so obvious to you, other people don't even notice because they don't care. You're not in a spotlight on stage, you're just one of many walking the street, watching a movie, riding a bus, etc.
