If it makes you feel any better, my wife is taller than I am. She's just at the 6 foot mark and I'm 5' 9", which means that I have to tilt my head up ever so slightly just to kiss her. And when we hug, she has to lean her head down on my shoulder in what must be an uncomfortable manner.
When we first met I thought, "fuck there's no way this chick is going to want anything to do with me from the waist down" and we sat and talked over coffee. The second time we met we did the same thing. Then we went for a walk. She showed me how to slack line. If you don't know what that is, it's when you tie a flat rope from one tree to another and tighten it and try to walk along the rope like a tightrope walker. It's hard as shit and terribly tricky to master. Obviously taller people excel at that with their center for gravity being higher up. I tried it and immediately fell flat on my chest, knocking the breath out of my lungs.
I thought "if she did want anything to do with me before, I have surely extinguished all hope". Turns out she was thinking "omg this guy is never gonna talk to me again". That same day I fell in love, as did she. And here we are today.
My point is don't give up hope. Shit, don't even think about it. A woman you deserve will recognize you for who you are and she'll love you and your slightly below average height. Keep being yourself and you won't ever have to worry.
