Is nudity sinful?

This post will be a little personal so I’ll try not to go as deep—so im in a long distance relationship and, honestly, it’s going very well for me. However, my partner isn’t religious the way I am or isn’t religious at all which is fine by me because I don’t think it’s wrong to date someone who has different beliefs. However, it’s got me thinking a lot about how long distance people interact in a sexual way / manner and im wondering if it is sinful to see your spouse or someone you are committed to naked? I know that’s a weird question probably, and I don’t mean to ask this on some subreddit but honestly I don’t know who id ask…it feels weird to bring this up to my pastor and to sit down and have a conversation about this.

I know that pornography and stuff I think personally can be sinful if you are addicted and are sexualizing / objectifying whoever you are attracted to, but what if you are doing it with someone who you are dating? Or someone who you plan to stay long term with? Is that sinful because looking at someone naked and romantically / sexually being attracted to them is wrong? I don’t know if this post will get any attraction but im just hoping it reaches the right guidance / anyone who can guide me on this. I’m aware the Bible doesn’t address issues like this because the Bible has specific purposes in each texts, so, the authors probably weren’t thinking about phones or anything like this in their time. Anyways, thank you to whoever is reading this and I hope tomorrow you all have an amazing Easter!
