This might be completely unrelated, but let's give it a shot:

I've noticed that sometimes after spending extended periods of time (in the magnitude of hours) in very close proximity with a significant other (e.g. cuddling, kissing, etc.), I feel groggy, dizzy, and have brain fog/difficulty focusing.

Could this be related to CO2 levels? I've been feeling it today and was wondering if it is hormone related, but CO2 could be an interesting explanation as well - I have noticed my breathing tends to slow down during these times as well.

I've never heard anyone else describe this so if you have any similar experiences, please share so I don't feel so alone with this.

There's a lot going on physiologically when you're getting intimate (e.g. oxytocin, testosterone), so it's hard to tell. However, I've noticed the same thing, and I'll also add a loss of appetite.

Glad someone can relate, but sorry you have to deal with it as well.

What are your thoughts on seeing an endocrinologist about this? In addition to oxytocin, testosterone, etc., I was also wondering if it might be related to prolactin levels.

I also just read some people talk about similar symptoms here but no clear answers: https://patient.info/forums/discuss/partner-becomes-ill-afte...

I had that happening. For me it was an allergic reaction which slightly blocked my sinuses and reduced the air intake. The allergy was previously undetected because I do/did not use the same cosmetic products that my partner uses. A antihistamine nasal spray may help, but check with an ENT.

Interesting, so does that fall under the category of "mild hypoxia" or something?
