Help me :(

Okay so I’ve always been really insecure and I don’t like watching movies with a bunch of nudity in them it makes me feel weird I have zero desire to see actors and other people naked. And I get really awkward when I watch a movie with my boyfriend when you can see a girls tits hanging out and stuff and he doesn’t think its a big deal but I just feel weird and I get super insecure and I wish I didn’t. Is it normal for me to get so uncomfortable seeing that and not wanting my boyfriend to see it? I’ve been raised very Christian and I feel like my significant other should only need to see me in any intimate ways because it’s special, but he feels like it’s not a big deal and I shouldn’t get uncomfortable because it’s just a movie :/
