22 yo male with bad genetics? Me out.

Hello, I am a 22 year old guy. Now, i have some serious doubts about myself. My body stores fat under my arms, 'lower belly' and buttocks. As far as I have known, males have a tendency to store fat in their belly and not underarms or something. Also I have gynecomastia. I have facial hairs as well, but its not completely covered my face. There are still a few patches which I don't think gonna be coming in future. I once was concerned about klinefelter's syndrome so I went to the doc and he did a FSH test which came out normal so he said that I am Klinefelter negative. But still, when I look at other guys , I am able to tell the difference. Recently I did ketogenic diet and went till 76 KGS , after leaving it, and just having good home food (maintaiance calories) , I have gained 4 KGS in a few weeks. What tests should I perform so that I can know what the problem is. Also I have a elongated face shape which doesn't match with usual shapes. Don't know if its relatable.please help me out.
