What does arousal feel like to u

hi does anyone ever get a random grounal response then feel aroused but you don’t want to be like before i had the thought i was feeling a little aroused then i had a random thought and it had the ground response and i felt aroused i don’t understand.

Hey guys recently I been facing anxiety because I have a fear that I acted on something I know I didn't do but it feels real because it felt like I had attraction and arousal to a younger photo of a ex gf I feel so weird feel so anxious I need help Idk what to do

When I say I feel like I like a thought, I don’t mean the OCD is telling me like a thought or that I concluded that from a physical sensation. I mean, I genuinely feel like something in my brain lights up and it feels like I like it mentally. Whenever I hear people talk about liking thoughts (excitement, arousal), I always see things about groinals or heart flutters. Physical things. I don’t think I really ever see people talk about the mental sensation if this is even a thing. I just wanna know if anyone relates to this or has found an explanation for this because seeing it from an analytical point of view seems to help me sometimes. This is so, *so* especially hard for pocd themed thoughts :( Anyone relate?
