This is actually two separate images. The image on the left is masculine and the image on the right is feminine. First I created the image of the girl. I used the pen tool to create the silhouette. Next, I used the font Giddyup Std for the world "girl". I then used the expand tool and pen tool to manipulate the text and draw the squiggly lines.
For the man, I actually reflected the girl's silhouette and then used the pen tool to make some minor adjustments, creating the man's silhouette. Next, I used Myriad Pro to write the word "man". I didn't manipulate the text at all, because the font was exactly what I pictured in the first place.
