Silly Christo. Of course Peter's a chick magnet. His naiveness (That's a word, right?) and obliviousness to romance/general awkwardness are what make him so endearing and irresistable. Or that could just be me since I have, as my friends put it, a "fetish" for that kinda stuff. XD
I really love what this says about Peter. It applies to a lot of guys, actually. I don't mean to always make this reference, but I even kind've accidentally linked this comic to my friend and he has spent every waking minute catching up and regaling me about what Peter just did. As if I didn't read it years ago, but still, I understand how joyous a thing as discovering Pictures of You is.
Anyway, back to my point. It kind've says that Peter isn't really as aloof and naive to everything they think he is.
Now maybe still to someone being gay, but that is for a different chapter I believe.
