I was finding it amusing and entertained him by not being rude. But I did remind him every now and then that I was straight. Then he messaged me that ...he wanted to eat me up. I did find that statement a bit of a turn on. I responded with a “lol”.A few minutes later I got a pic from him, it was him in a black lacy panty and bra, he tagged it with a message saying “is this girly enough to get your straight juices to start flowing?”It was a hot selfie, with him posing in a girly manner, he was.
