What’s wrong with me

Hi this post is going to be a bit tmi but I honestly don’t know what to do.

I’ve had crushes on guys throughout my life and I always want to makeout with guys at parties. But whenever I do it feels like I’m kissing a wall, I take no pleasure in it whatsoever.

My eyes are closed of course but my head doesn’t go blank or anything of the sort, I start thinking about random things. Most recently I was making out with a guy in his car and I was planning my beach hangout for the next day with my friends, I was also thinking about some errands I had to do.

It was lasting so long that I literally thought, “would it be weird for me to get off him and wrap it up. Oh but wait he’s clearly enjoying it so I guess I need to continue”

He tried to pleasure me but I was bone dry and so I told him to stop. When he finally finished I waited a couple more minutes of making out and then I asked him to take me home, he seemed surprised but did it anyways.

Every single time I’ve hooked up with a guy it’s been the same feeling of just being anywhere but there in that moment.

I don’t think I’m lesbian because I’ve only had crushes on guys. I also get horny often, I really want the idea of hooking up with a guy, but every time it happens I just want it to be over.

Is this what being asexual is?? I’m so confused. Can this change?

Please, I don’t know what’s wrong with me but none of my friends feel this way, they all enjoy their hookups and I just don’t know what to do.
