I’m not attracted to my girlfriends body.

For context, I (15M) met my girlfriend (16F) a few months ago. She was attractive and I think we instantly clicked, our personalities went great with each other.

I saw her body yesterday for the first time and I didn’t feel any attraction to it. I had to force myself to pretend to be amazed for her sake but I really wasn’t at all.

Any advice for what I should do? She is so great but yesterday really threw me off.

Edit: She isn’t even fat or anything, I just didn’t feel anything when I saw her like that. I find her face extremely attractive

Also, I haven’t watched porn for about a year. Don’t think it has skewed my perception

Edit 2: it’s not an online relationship. We originally met in person and I saw her last night in person

Edit 3: I feel that I can’t just break up. It’d feel like something was missing, idk. I am very attracted to her personality, she’s a great girl but I just wasn’t physically attracted to what I saw yesterday and it felt unnatural trying to force myself to feel good about it

I honestly feel pretty depressed about the whole situation because I really dont want to hurt her feelings, she doesn’t deserve any of this but at the same time I don’t want to be keeping secrets from her

Edit 4: guys, I’m not gay

Edit 5: for some clarification, when I say seen her body for the first time, I mean naked. I’ve seen her before with clothes on but this is the first time I’ve seen her without them.

Edit 6: I’m going to sleep it’s 1:24 in the morning, why tf did I stay up this long
