"I know how to get l--" No, Rex. Don't even try. He's only ever gotten laid in spite of himself, not because of any efforts on his part. He glances down and drinks quickly. "I'm not looking to get laid. Especially not..."

Here. He's going to say 'here,' but he stops himself as he spots a woman out of the corner of his vision. At least, he assumes she's a woman, based on the choice of clothes. She's lacking... mammalian secondary sex characteristics, so he can't say for certain. Hairless, her skin's a bluish-gray, save for a stripe of orange beginning at her throat and progressing down into the plunge of her top. The coloration calls to mind the ringneck snake, so...

Rex is just staring at her the way most men would stare at the stripper Cindy tried to send to him.

And then, after a beat, Rex realizes that he's probably being rude and quickly turns back to Cindy.

"You're right, I don't know what I'm doing. Can I buy you a drink? To make up for..." He waves a hand in a vague direction, as if to somehow communicate "the lapdance."

Yes, this will hide his fixation on non-human women very well.
