I can't say that I have been aware of any real change in my sexual outlook so far, but I do think that shifts in our hormone balance can be very subtle and yet profound. When I first started TRT I found myself subject to really bad mood swings, getting angry or upset for no obvious reason. What brought this home was one day when I was feeling down generally and just burst into tears for no reason I could fathom. This was so unlike me that I was really worried about it. My doctor suggested that it would settle down in time, and so it has, but it left me surprised and a little suspicious about the extent to which our hormones shape our actions and behaviour.
I'm only a few years into my personal gynecomastia journey, so this is all new territory to me. Physically, I'm still growing (slowly, thankfully) so I can still wear many of my shirts without too much trouble. I stick to the loose-fitting ones with strong patterns to try to disguise the breast growth, though I can certainly see that this will probably become impossible in time. About half of my shirts I never wear now, either because they are too fitted, or because the material or pattern emphasises my 'assets' a little too much. I never wear T-shirts or polos now because they make my chest to obvious. Of course, wearing a bra does increase projection a bit and exacerbates the problem. If I am realistic I will probably have to get rid of most of my current shirts, but I'm still clinging to the hope that with exercise and diet my boobs might go away somehow.
I do have problems with my remaining 'stealh' shirts pulling tight across the top, which in turn means that they gape and tend to show my bra unless I am very careful. I find myself having to surreptitiously rearrange my boobs from time to time to counteract this, which is not always easy to do in public without drawing even more attention. Sports bras can almost be worse than conventional underwires, in that they are invariably visible with a couple of shirt buttons undone.
I don't have a problem per se with the idea of wearing panties - like Johndoe1, I'm wearing a bra after all. I don't get on with boxers and never have, so I tend to stick to briefs. Maybe I should give panties a try sometime, and perhaps women's tops would be the answer to the gaping shirt problem. Given the altered reality we have already embraced in wearing a bra, it would be pretty strange to then make some arbitrary judgement regarding all other women's clothing.
I would definitely seem that to persist in wearing what has become ill-fitting clothes due to breast development will only serve to draw attention to our condition, just as the movement when going braless does. I did wonder if the current women's fashion for 'boyfriend shirts' might be a possible compromise between a better fit and a less girly appearance. I have not investigated this yet so have no idea whether I would be able to get them in my size. Has anyone tried these? Does anyone have any other suggestions for better fitting non-gendered clothing that might be worth exploring?
