What constitutes as asexuality?

Until recently, I believed I was pansexual. Today, while I was reading some yaoi manga, and, well, touching myself to it, a thought occurred- I will inevitably get married, and will have sex with my partner. But the thought grossed me out. Not only the thought that someone would be touching me, but the thought of touching someone else was very repulsive too. This is strange- my love language is physical touch, and I love giving people hugs platonically. I have also kissed my friends on the cheek a few times, or on the top of their head, all platonic. But the thought of touching someone sexually is grossing me out. I'm a virgin, but I've had my fair share of partners, though it never went past hugging. A few tried, but I refused, and we broke up. Does this count as asexuality? Also, I don't feel the same way about fictional characters, but I don't think I'm fictosexual.
