Am I asexual?

Am I asexual? I am asking this because I am really confused about myself and I can't even ask my family as they are very close-minded. When I read about sex, watch clips of it in movies, listen to it, and even watch porn, I never get turned on. I actually get bored with them. When I like someone, I've never really thought of having sex with them and mostly think about what it would be like to be with them instead. And when I do think about doing the do with them, I feel uncomfortable like there's a pit in my stomach or something and I feel nervous? There was this one time a friend of mine accidentally touched me a little close to my chest and it felt so wrong like it burns, but it also feels cold or something and I feel strong shivers at where they touch. But I'm alright with hugs and kissing though, just not with the intimate touching and stuff. Is this normal? I thought to myself that I might just not be ready, but I feel like I would never be ready. I told my best friend about this and they said that I might be asexual but that they are not sure since they are not one themselves. Am I just over-reacting? I'm sorry if this looks like a dumb question, I live in a very narrow-minded family in a very narrow-minded country.
