I had to stare at it for a few min to see what he's talking about. I see it now. After a few min, knowing where to look. Sometimes seeing someone in person, these things stand out more to be fair but I suspect this is a case of being too picky. I don't blame him for asking, anything minor to fix a problem that bothers you is ok. But I don't think such a solution exists here. This is a phase and you'll grow past it in a few years. The law of diminishing returns applies here. The more you do, the less benefit you get. As a guy, you have many more options as well. You can dress up, build your upper body, or make a lot of money. It becomes easier after mid-20s especially. I have some ugly, ugly friends who have some very attractive spouses. And they're not trophy wives or housewives.
In the mean time, I'd suggest running some experiments to prove to yourself that it's not a problem. Post the pictures to Mechanical Turk like I suggested and ask people to rate. Touch up the photo in Photoshop to fix the problem and then resubmit. I'll bet you real money the ratings are almost identical.
