Questions: Guy's Behavior

I have started conversations with multiple people and they have all told me that the woman with surgeries and voluptuousness is the ideal woman, the meaning of a true woman. How true is that?

I am a woman without surgeries, I am not socially pretty or attractive, but I have never felt ugly, that's where my question comes from, is it possible to feel like a woman without having surgeries?

I was born a woman biologically, but I don't feel like one, the current beauty standards make it difficult, it makes me doubt myself, and at the same time it makes me feel bad since I don't feel feminine or that I have value as a person.

So there’s this guy in my class, who I sit behind of. I got to admit his kind of attractive but that’s it, he’s style is good and he’s eye catching so I be staring at him sometimes at class so I be seeing how he acts, now that seats changed I sit behind him and lately he turns around and we make a small eye contact (there’s no one behind me) and he touches his hair a LOT, especially today. He was fixing, touching his hair every 5 seconds and it really started distracting me to be honest. Then later his friend talked to me because we got class together and he was smiling and giggling at me while I was speaking to his friend and yes we had a small chat all together. I sometimes feel he be staring at me in both classes we got together but I might just be crazy. What do you guys think?
