Do guys only date girls because of their looks? I have never dated before but sometimes that is how I feel about them. I feel like they only date them cause of their looks and it doesn't seem right to me. I don't know but that is just me.

No, not really. I personally try to get to know a lady and see what their personality and heart are like. If I like those parts, the looks are just the outer dressing. 

The lady I love so much right now is the sweetest woman I've ever met. Plus she's good looking too. Heart and personality come first! Looks don't matter if they have great hearts!
