This was reported for removed attribution. However, no, it wasn't, and it would've been somewhat difficult for the OP to find the source if they didn't know the name of the comic series (Mr. Lovenstein). In fact, the credit is there in the center – vertically situated between the top and bottom panels. Better safe than sorry, so I appreciate the report.

OP didn't say they tried to find attribution like Rule 5 says (assuming they didn't see it in the image, because god that's inconspicuous), but it's not the end of the world.

Literally me and one of my kinks. I love seeing other people grow stronger.
