Why don't all the girls you date want to take photos with you when traveling?

There are many possible reasons. Here are some possible explanations:

1. She may not like taking pictures: some people may not like taking pictures, or they may think they are ugly or troublesome.

2. She may not want to be noticed when traveling: some people may want to relax and don't want to be noticed when traveling. If she doesn't want to take pictures with you, it may be because she doesn't want to be the center of attention.

She may feel uncomfortable: if she is not sure whether to develop a further relationship with you, she may feel uncomfortable. In this case, she may not want to take pictures with you because she doesn't want to feel embarrassed.

She may not want to waste her time on traveling: some people may think that traveling time should be used to appreciate scenery and culture, not to take pictures. If she doesn't want to take a photo with you, it may be because she wants to focus on the tour itself.

For whatever reason, if you want to see her again, you'd better respect her wishes. If you think taking photos is a good way to commemorate the trip, you can try to ask her if she would like to take photos with you. If she doesn't want to, you can try to find other ways to commemorate this trip.
