Weird father / daughter relationship ?

Hi guys I’ll make this as short as possible, my fiancé has a 23 year old daughter. He is super close with all this children and it’s one of the things I admire most about him. We live a different type of lifestyle than normal homes….we live in LA so it’s very much about vanity, beauty, and appearance around here.

Anyway, his daughter sent him photographs from her photo shoot (she works at a huge entertainment place, bikini waitress and bottle girl).

The photo shoot was exotic themed so it’s her in a thong bikini dropping in jewelry and gold. They are definitely “sexy” photos and came out SOOO good! He was so excited to see the outcome because it was a $15,000 shoot.

When he came over to me to show me the photos I couldn’t help but get uncomfortable that he was seeing her in that fashion. I wasn’t jealous (god no) it was more of me not understanding.

So my question is, is that weird? Backstory on me, I grew up in a SMALL rural town and never met my father, so I genuinely have no idea what a father / daughter relationship looks like, or what it’s like to live this expensive lifestyle that I am now apart of. I’m not mad, It wasn’t even anything to bring up to him because I felt like it was a “me problem”.

So before I spoke on it I wanted opinions on the matter. I truly think I got uncomfortable because I just (literally) can’t imagine having such a close relationship with my father. I don’t want to project my own past trauma onto their relationship and make something of it that it’s not.

Besides that one encounter, I never felt uncomfortable. I always recognized how close they were but like I said he’s like that with all his children and I admire that. Especially since we are trying for our own child, I love how involved he is In their lives.

Thank you guys in advance for your opinions ☺️

Edit: thank you guys for commenting! I think I just needed to hear it from other women that it wasn’t weird. I never have / don’t think anything weird or sexual is going on between them, it was just an odd feeling in my stomach. But like I mentioned before, it’s probably just because their lifestyle is so drastically different than mine. He really is so supportive and gave his kids the resources to do whatever they wanted in life!💜 I’m not going to bring it up him, it’s truly not that big of a deal and was just a passing feeling/ thought☺️
