TITLE: I (F20) really enjoy the company of M20 but can't get past how tiny he is. Help?
POST: I've been talking to this guy for 3ish weeks now and I definitely am on the track to liking him as more than a friend. We have a ton in common, he's pretty attractive, and we have conversations that last for hours. 

My only issue is his height. I'm 5'4" and 3/4 and he's solidly 5'4". Me being almost an inch taller than him doesn't really bother me too much, but he's super skinny as well-- as in, really underweight skinny. He doesn't really look unhealthy, he's just small in stature. I'm more on the curvy side (not really fat or anywhere close to obese, but I have some meat on me), and I constantly feel like I'm going to break him or that I look morbidly obese compared to him. It's just a really big turn off and I'm really confused on how to go about this.

Like I said, I get along with him really well and we clearly don't have a problem communicating. I'm just having trouble being physically attracted to him because of how small he is.
TL;DR: 
I am emotionally attracted to a guy who is much smaller than me. He's physically attractive aesthetically and we get along amazingly, but I can't get past his height and weight. What should I do?
