My legs too fat for lotus?

I am a natural T-Rex. I exercise and run and my thighs were enormous before all this. When I get into lotus, it puts a lot of strain on my right ankle. I look at pictures of people meditating and it looks so natural with their long skinny legs but mine are short and fat like sausages and its really quite comical.

Today I took the ankle pressure off by getting my legs even more tightly knotted, basically, and enjoyed a really good session with some new insight on pain. Now my knees are tingly and sore, and I'm afraid to do this again. Are my legs just too fat for full lotus?
