Do some things that can make you more physically attractive. Things that are within your control like working out and eating the right types of foods. Drink water instead of sodas or sports drinks. You don't even necessarily need to do that to appeal toward women but if you do those types of things surely they will follow. I was a rather skinny lanky kid growing up and when I got into weight lifting in college I began to appeal to a broader range of women.
Also let me say I have been to many different places and have seen really great looking women and you see them and they're with some ugly ass guys too so don't ever doubt yourself either.
