This entire composition from start to finish arouses me. No, not in a sexual way. Yeah, storms and strong wind are incredible. Any kind of strong weather demands respect and reshapes your persepectives.
Maybe he was meaning that.
But seriously, what do you mean by arousing? sexually or more mentally than anything?
I love storms too, and rain. And like Amanda32 says, maybe if they're arousing, then by default they can be too sexual xD
One of the biggest turn-ons for me is emotional intimacy - defined as "opening up" sharing many personal things about each other in conversation. It makes me hard, even though there's nothing sexual about the activity.
