I know this may sound preposterous or superfluous but..

I'm a 18 year old male, My height is kinda tall in the perspective of height in my country (5'10 or 5'11). I'm kinda gloomy and has a serious face always. I know that there's a stereotype of girls love shoujo, romance and related to that but considering this I like reading these kind of stuff well I also like action and so on, but when I'm reading in public I'm ashamed to read shoujo and romance manga's.. Can someone give me an advice or something :<
