hi,
I think you are right in the assessment of your body. you need to bring a change in it if you really want it.
But as you said , the future guy will ......, it is the basic mispconception. You will be amazed to hear that some guys simply do not like boobs, even do not like to touch boobs. Some do not like big sized boobs at all. Some guys love square faces. So please, do not visualize things at your own. Your future guy might like you the way you are.
Second thing is that, the guy that is only interested in his imaginative figure and face, is never so much reliable to live with. As the most beautiful persons deteriorate with the age....so lost their charm and beauty one day. Always go for the nature inside the person - not the outer beauty and building...

hope it will help you.
thanks
