It's tough. Guys do have an idea of what the "perfect woman" looks like. I remember in a dance class meeting this woman who was my exact ideal of feminine beauty. After two minutes of her acting stuck up I realized that I was not in the least bit interested!
I think it's also imprtant to know that few guys ever marry the woman who is their idea of feminine beauty, but after awhile she becomes the most beautiful women in their world. As men we should do a better job being clearer about what "physically fit" or any other physical description means, especially making sure that women know we aren't looking for perfection.
Ladies, from your end please remember that guys are visual creatures- our first method of sorting out who we are going to ask is your looks. Online it's less easy, but if you inculde pictures of you doing fun things so that you personality shows through then that will overcome the fact that you might not be his ideal. Guys will go for a "less attractive" looking girl who shows visible signs of being fun to be around over a more attractive women who looks hard to please. What I am saying is that good looks will get you to the front of a guy's line, but they won't keep you there very long! Also, different guys like different kinds of feminine beauty. So even if you don't fit the ideal, it doesn't mean that you should hide who you are. The guy that God meant for you is going to love you not despite your body, but because of your body and your spirit. So don't hide! You are beautiful!
