Wanted to try something but girlfriend backed out. Need advice !

Wanted to do exhibitionism of my gf. She was kinda open to it and we did a lil spicy semi and nude photoshoot and all.. but when it came to posting, she suddenly backed out after seeing the posts and stuffs people post in these subreddits.. she got startled and weirded out i guess.
I respected her decision of not to post at the moment and asked her to take her time and surf through the various subreddits and get accustomed/comfortable with reddit and these posts which she agreed half mindedly but i don't know for sure.
What to do.. experienced people/guys/girls.. kindly dm. Any ways to convince her..?
