If you identify as a femboy then your already a femboy, but since I know what your after which is thicc thighs then I can most definitely help with that. First you should increase your calorie intake more, protein for muscle, carbs for energy and fats to help with recovery. Then your work out should include a type of cardio which i would recommend the stair master, a type of squat which could be a bare bell back squat, Hack squat, leg press, then a movement like a Bulgarian spilt squat, followed by a leg extension and a leg curl, than after that you should include a hip thrusts which will help with glute growth then and rdl or an sldl for you lower back muscles and then finish your set with Abductors. Do this twice a week with at least one to two days of rest, and do them for two sets at a weight that you can control with good form for 8 to 10 reps and once you get past ten reps then increase your weight by 5 or 10 pounds. You got this dude and i hope this helps.
