Is it normal to wanna get in her panties?

So I was sitting in my truck in front of the restaurant waiting for my crew to come out from eating breakfast. I was watching a beautiful slender young woman crossing the street in front of me, wearing a long flowing almost floor length dress. I was thinking how out of place she looked dressed like that so early in the morning, when suddenly a gust of wind blew that dress so high I could see her lovely ass cradled by a dainty lacy sheer lavender thong, and the first thought on my mind was how lovely she looked. She flashed me a big smile like she was enjoying it as much as I was. Didn't look at all embarrassed. My second thought was "I'd love to get in her panties"! I mean, I have dozens of pair of various women's underwear, but I don't have a lavender sheer lacy thong yet. Is that normal?
