I've got smallish breasts that are ultimately just man-boobs. They're somewhere between an AA and A. When I was young and thin, my chest was totally flat with very little pectoral muscle or anything. At one point in my early to mid thirties I worked a physical job and worked out in the gym and actually had a V shape and pecs. I moved to a less active job and away from the gym and everything got softer. But, I never really noticed anything that resembled breasts until I saw a shirtless photo my wife had taken of me from the side. That photo was taken a few years in to my dressing.

Well, my natural breasts have come to look and feel more and more like boobs rather than leftover pectoral muscle. Taking off my bra tonight and looking in the mirror I saw my breasts in an even more significant light and it brought some questions to mind. I'll give a timeline before I get to my point...

In the early 2000's I began testosterone replacement therapy and and have continued taking injection since then. The injections started a couple of years before I ever contemplated wearing anything from the woman's department. One of the major potential side effects of TRT is breast growth. Seeing my boobs in the mirror tonight got me to thinking about the potential source of the growth. And, that led me to wonder if the same underlying cause could be encouraging my feminine aesthetic.

I am just wondering if anyone else has any experience with TRT and could relate the timing to the beginning of their crossdressing. It could obviously be a total coincidence, but it could be a cause/effect scenario.

I'm not bothered if it's the outright cause and just the possibility makes me feel more justified in having my taste.

One side note, the testostone has increased my body hair and beard A LOT. I always wanted to grow a beard, but never wanted to have a hairy body. So, my beard is long and much of my body hair is shaved with every shower. The stubble in certain areas is just too intense to deal with and my wife prefers a certain amount of body hair. It's where we compromise...
