I'm glad it works -- I have a hard time writing sex for these three, I don't know why. I did love the idea of poor Neal not having much control after a long time celibate -- I mean obviously there's his own hand, but it's different when you're getting a lot more touch-stimulation. I think he'd be faithful to Kate, and we certainly have no evidence in S1 that he messed around with anyone else; he's not physically very close to anyone but Peter, so it made sense that he'd be a little overwhelmed.
