Cross-dressing, Trapping

There is nothing wrong with leg muscle if it's covered up with a little fat. Running is not going to give you bulky arm muscle, unless you are doing hand-stand jogging.

Especially not if you are burning more calories than you take in. As a general rule of thumb, figure about your weight x 10 is your baseline calorie needs. So if you weigh 150lbs, you need AT LEAST 1500 calories just to keep from losing weight. A 150lb person who isn't lazy will likely burn 2000+ calories. In other words, if you eat less than that and don't do much heavy lifting, muscle bulk is going to gradually go away. Tone muscle = fine. Bulk = bad.

If you start HRT now, it will only accelerate your progress in terms of slimming down. Having testosterone makes your body more prone to preserve muscle, but catabolize fat. Vice versa.

A little excess fat is good. It will help the process along. You What would said would be like saying "I don't have any boobs, so Im going to have to get a boob job before I even begin HRT"

You don't have to go pure vegetarian to get skinny. I still eat red meat maybe one or two meals a week. Excessive protein and caloric intake is what will preserve muscle bulk. Don't cut protein out completely though. It is really unhealthy. Especially for the hair. ;)
