Man, you dropped the ball. Don't ever make public displays of affection to women in your work. Its foolish. School boy error.
If anything, be ambiguous, vague, indifferent, and let women initiate. The juice is never worth the squeeze IMHO and experience. Its a headache and it is never casual no matter how much they try to say it will be. Furthermore, you cannot bring out the violin and cry foul. She can always play that victim narrative and destroy your career.
In the predicament I shared, I took her home, a male coworker caught her sexually harassing me (in the event it went to HR), and furthermore, I video tapped going 15 rds from 3am till 6am back at her place. The video tape on my phone was renamed "coffee." What she invited me in for after the pub.
I wish things were different. Like, I wish this was not a scenario one would have to worry about but, I always archive text convos, screen shots, snapchats, nudes, emails etc. in the event things go tits up.
If you play with fire, you will get burned. In all probability, if you have a video on your phone of clapping them cheeks, she is less likely to go to HR after though, she could call it blackmail even still. best left undone.
