Confused about different attraction-related sensations for different genders

So I’m questioning my sexuality. I feel very strange. I’ve always thought I was straight but now I find two different sensations when I feel things towards men and women.

For men: I see an attractive man on the street and feel my heart clench. It’s like a shot of lightning. I would think this is attraction, but when I go home and actually think about being with a man sexually, I feel so disgusted. I feel like I dislike male bodies, such as when I see (fit, attractive) shirtless men on the beach.

I have never fantasised about being with a man sexually. It was always this blurry idea of a “person with a d**k” with the focus on them wanting me than me actually being attracted to them. It seems comphet-y?

For women: I see so many women who I know I’m attracted to. It’s not the same with men. I don’t feel the heart clenching feeling, just a warmth in my chest and a bit of excitement in my belly, making me want to talk to them and flirt with them. My fantasies with women are crystal clear, I definitely know what I like.

So am I experiencing comphet? What do you think the clenching feeling when I see men is? I was thinking maybe it’s anxiety or fear, but I’m not sure if that’s from my attraction to them or just fear of men generally.

Anyone ever experience different sensations of attraction to the different genders?
