Why did none of the girls at this party want to take pictures with me?

So yesterday I went to a nice party, at a charity.
I have been there every now and then for 7 months.
I met many girls over there, but never approached anyone.
I was good to everyone , made them laugh
At least once.
There were many guys who got a picture with me because I approached them.
But when I approached all the girls who I have interacted with, they all seemed awkward or said yes but didn't want to be in the same frame, I could see how they smile for all other people and when it was me , the smile was forced.
After some of them did that I didn't asked anyone else.
It wasn't like I wasn't dressed properly.
I was in a suit. Good hair etc.
It made me feel like I don't have them as friends they were just some I know.
