This is a pretty silly suggestion, but I thought it was a fun one, so I'm throwing it out there. 
The suggestion is just as the title says - Your character face generation parameters could affect you initial chemical romance score with all eligible individuals. Sliders at either extreme tend to make a character fairly ugly, so a character with lots of extreme parameters should get a negative score to their chemical romance. On the other hand, characters with more average face scores are usually more attractive - They should perhaps get a positive score.
Age could also be factored into this.
