I love contrast too! Not only actula physical contrast, but also going in opposite directions..
My ex-girlfriend was a very good looking girl, just a bit on the chubby side when we started dating, while I was very fit and muscular, being an athlete.
My friends too used to tell me how good looking my girlfriend was, just a bit too chubby.
High school was finished, we moved together, and my training shedule became much less important.
Also she was cooking every day, and presenting me great dinners. I was completely absorbed by her and our relationship which I didn't notice the initial changes.
I notice she was losing some of her extra weight, also because her friends were complimenting her for it. Despite being a fat admirer, I was so in love with her which I didn't mind too much.
After a few months she confessed me she was in love with how I was getting. I asked what she meant and she shocked me. "You are getting soft.. your abs are no more in sight.."
I was overwhelmed with emotions. I was getting "soft", my girlfriend was getting better and better, everyone were noticing it, I was totally unaware of it until it was too late.
That summer I was the one getting amused comments about my soft potbelly, while my girlfriend kept being praised for her wonderful body!
Does it count as a contrast??
