Is it normal i hesitate in front of beautiful women and then have regrets later
I walked into a Best Buy store today (12.5.2015) to buy some headphones, and I grabbed one that was white Sony. I checked on the shelf and it said 13.99. I brought it the counter and the cashier girl was very attractive, with medium length brunette hair, and her blue uniform looked very good on her. She was around 5 feet tall and looked slightly Latin. She looked young like she was in high school. So she scanned the item and asked me to pay 32 dollars. I knew something was wrong so I told her hold the white headphones and I would be right back. I returned with an almost identical pair of Sony headphones but this one was blue. She scanned it and said this one was 14 dollars.
She gave me a puzzled look for a second and said "that's so weird". She asked me to take her to the aisle where I found these headphones. So I took her there and showed her. The white headphones were indeed 14 dollars. She bent down and removed the old price sticker for whatever reason. Then she led me back to the counter. As I walked behind her I could see that despite her small frame she was quite curvy with a very impressive posterior in those black pants. She asked me whether I wanted the blue or white headphones, I asked her how much the white one was, and she said 14 dollars. So I decided to go with the white one as it was slightly better quality.
I paid her a 20 dollar bill and she handed me back my change. I said "thank you very much" and she said "have a good day". As I was walking out of the store, I thought about how I could have handled that interaction a little better.
I am autistic and never had a girlfriend. I really wanted to flirt with her because she was attractive and nice but I didn't know how, or even if it was appropriate in that environment (although there was no one around us and no customers in line behind me). Anyway I thought about how I could have at least tried to make her laugh. I just get really nervous in front of attractive girls and my heart starts racing and I can't think straight. I can't show my personality or sense of humor and I get stiff and robotic and awkward. Then later I always have regrets about how I could have done or said something differently.
