Usui Ayumi's Favorite

This is a thing that I've noticed but ignored up until now. I started reading Manga since I was in middle school. So my mental sexual maturity had sprouted since young. The problem I have surrounding that is if it's normal to not feel any sense of sexual gratification from real life sex senses.

I must also mention that I did explore porn sites since younger also. Probably around the same time I started reading Manga. But I have never found actual real life people porn stimulating. Compared to reading novels that describe the action or Manga that gives you a panel by panel portrayal, real life sex has never been anything appealing. To the point where even a simple scenario of exchanging lips and saliva with a significant other in real life fills me with boredom and disgust. Not that I've ever dated or experienced what people call "love," anyway.

I'm at an age where I see my fellow university peers finding love and whatnot. But that desire alludes me. Is that a common feeling amongst some people? Or is this feeling just me having a form of a lack of emotional and sexual empathy, ie, mental issues?
