So my gf 23F I am 27F straight male - she keep mentioning her often

I want to ask bisexual women and women who are very comfortable with their sexuality.

I’m trying to understand a pattern I’ve noticed with my partner.

There’s a particular actress (let’s call her Actress A) who my partner LOVES. She always suggests watching movies of Actress A, knows her roles, knows when her next projects are coming out, comments on how soft, delicate, or feminine she looks, etc.

Here’s the part I’m confused about:

Whenever we watch movies with Actress A, my partner gets noticeably more turned on, more passionate, and the sex afterward is way more intense. She even initiates more, compliments the actress openly, and sometimes can’t take her eyes off the screen when Actress A is in a sensual or emotional scene.

She’s very smart and usually aware of everything, so I’m sure she knows I also find Actress A attractive but she still chooses these movies.

My questions for bisexual women or women who understand this dynamic: 1. Is this common? Does being attracted to a specific actress create that kind of emotional/sexual amplification? 2. Is this bisexual curiosity, admiration, fantasy overlap, or something else? 3. Is it possible she’s turned on because both of us find Actress A attractive? Like a mutual-obsession turn-on? 4. Could it be a fantasy projection thing (threesome fantasy, identification, or hybrid attraction)?

I’m not looking for validation or judgment. I just want to understand what this behavior usually means from the bisexual/queer female perspective.

Thanks in advance
