I don’t think it’s any different from saying that your newborn is cute or someone’s toddler is a cute kid. It has nothing to do with sexual attraction to the child. Now, I don’t know if your BF is looking for sexual attraction to his younger self. I’d suggest asking probing questions as to the answer he’s looking for. Communication is key to any and all relationships

What is up with you man? First the asklemmy now here. I hope all is well?
