Romantic Gallery Portraits

I am noticing in the gallery that some of the uploaded sim couples are in very romantic poses, but my game does NOT produce such portrait poses with my couples. Is there a mod that is doing this? I see portraits of couples forming hearts together with their fingers, couples leaning back into each other reaching their hands back and several other romantic cute poses. If this is due to mods, I would love to know which mods are doing this, because in my game, you can't even tell that MY couples are couples in their portraits. Thank you!
