MAFS: The real reason Mark won't have sex with Ning

"We talk all the time, we trust each other... but you know, there's still one more little incy bit that you need to have in a relationship," Ning hinted to producers.

"Maybe a few more glasses of wine and yeah."

But Mark's mind was in a completely different space.

"I wish we'd started liking each other a lot earlier," he told producers, adding, "it would've been a lot easier making these decisions."

"Let's just enjoy our romantic night together and you know, whatever happens will happen," Ning then told Mark.

Adding, "I think you should trust that."

But Mark wasn't budging.

"I just feel like there's bigger conversations that we need to have before we get to that stage."
