Is it normal when a short fat girl is stronger than a tall skinny guy?

I had one girlfriend in particular awhile back. She was a short fat girl. In sharp contrast, I was a tall skinny guy during the time she and I were together. I am still skinny but I was even skinnier back then. Standing a tall, towering 6-foot-1, I towered way over her (BY MORE THAN A FOOT!!!). She stood only 4-foot-11. However, she far outweighed me. She weighed A MASSIVE 190 POUNDS!!! I weighed a measly 125 pounds. One day, while she and I were at my apartment, she noticed that I had a barbell set so we decided to engage in a weightlifting contest to find out which one of us was stronger: Her? Or me? We both decided on the clean and jerk which involves lifting a barbell up over the shoulders from the floor and then lifting it up overhead from the shoulders. I normally had only a few small plates attached to the barbell so when I set it up on the floor that day, I added a significant number of larger plates. The newly-adjusted barbell weighed almost as much as I did!!! She was confident that she could easily lift it over her head while she figured I was too skinny to lift it over my head (even though I stood way taller than she did). I went first. While she was watching me, I grabbed the barbell and then I lifted it from the floor but when I tried to lift it up over my shoulders (while she continued to watch me), I couldn't even lift it above my thighs. I became embarrassed because as tall as I was, she could easily see that I wasn't even strong enough to get it above my thighs!!! Then it came her turn. I watched her while she grabbed the barbell from the floor and then I continued to watch her while she easily lifted it up over her shoulders. I was amazed but I became even more embarrassed because I already knew I lost while she won. I continued to watch her while she easily lifted that barbell right up over her head. I just stood there, stunned and almost in disbelief while she continued to hold that barbell high above her head (further demonstrating her superior strength over mine!!!). After all, I was tall and male while she was short and female. I knew that as easily as she lifted that barbell up over her head and held it there, she could just as easily have lifted ME up over her head and held ME there!!! I immediately conceded defeat. I knew right then and there that I was easily outlifted by her. Afterward, she and I stood in front of each other. I was looking way down at her while she was looking way up at me when she and I suddenly began kissing each other tenderly and passionately while we both proceeded to caress each other. We then walked over and lay down on the sofa where the kissing and caressing continued. It was still early in our relationship so that was as far as we went that day. Her being a female who proved to be way bigger and stronger than I was (even though I am a male who stood way taller than she did) actually turned the both of us on. We were afraid to admit it to each other until her lips and mine locked at that moment. It STRENGTHENED our relationship (PUN INTENDED!!!). I believe that as a rule, based on my own personal experiences with short fat girls who became my intimate girlfriends (like my above-mentioned girlfriend), it is normal for a short fat girl to be bigger and stronger than a tall skinny guy, especially when she is way bigger than he is (even if he is way taller than she is!!!).
