Yeah you read that right. Is this a sign of crazy?

Little back story we occasionally pass by each other at work but I did not meet her until recently. She's pretty hot but today at work someone said "wheres my dick pic"? I asked wtf he was talking about and he explained that people "know you sent a dick pic to ****".

I know she's really into me and we were planning on fucking soon. Am I overthinking this? I feel really weird for some reason. almost, betrayed? I've never sent a dick pic once in my life that's not really me.
