>>94313207His primary love interest for decades was girl much smaller and younger than himself. IIRC, he was 18-19 when he first joined the X-men and Kitty was 14 and started crushing on him immediately. The fact that Pete was like 6'5" and she barely 5 foot made the difference even more pronounced.
Now to be clear, Pete was never the one coming on to her, he's too shy and well-mannered for that, but she kept on until he finally returned her affections.
But the age and size difference always make it seem sketchy to those that don't know the context, i.e. everybody who likes to deliberately take things out of context for the sake of having something to bitch about.
