Why does my boob job look so natural? Is it a bad thing? (Photo)

The only opinion that matters is your own. If you are happy with the outcome then enjoy them. Best of luck. 

Thank you for your question and photograph.  Ultimately, despite the comments that either surgeons or your boyfriend give you, the only person's opinion that matters is your own.  If you are happy with your breasts' appearance then enjoy them.  It is impossible to know if you will need a breast lift in a few years, but given enough time, your breasts will eventually sag, as would non-augmented breasts.  At that time you can determine if you'd like a breast lift.  Best of luck to you!
