Psychology: Do I fit a category of Narcissism?

Male, 21
I was wondering if I fit a certain psychological stereotype. I'm a postgraduate student, ambitious, and I used to be rather fat during my adolescence. However I changed that around and got into fitness. I'm obsessed with training to the extent that if I go to McDonald's I will force myself to makeup those extra calories in training. I believe I'm good looking and have been told so, yet still I will have times were I completely lack self confidence. I cherish complements to fill my ego and I do unfortunately look down upon some, yet I still admire those who have achieved. I have researched narcissism and I seem to hit a few benchmarks.

I'm confident in certain situations such as work, home and places where I feel I'm control. I like to show off, expensive clothing, reputable job, motorbikes, adrenaline sports. However to me I feel like I do these things as ways to broaden my mind and social life. I need friends in my life, without social company I get bored. I get bored of girls easily as they don't have the same interests as me. For example I left my last girlfiend as she was racist to my housemate.

I enjoy relationships but I like space to do my own thing, I'm confident in the bedroom and that also fills my ego. I do a lot of stupid stuff and like to be centre of attention, Get terrorised by friends over the bad decisions I make yet I take it well.

I'm kinda just testing water and seeing if anyone could categorise me through this short intro
