'Jenny, do you have any lingerie for Deedie?' Candis inquired.

'I have lots of flannel, I have lots of gingham' the author joked.

'I think the pink and black would be good for you... look at how gorge - with these thigh-high stockings,' Candis continued as she held up a pair of nylons.

On last week's episode Jenner admitted that the only thing holding her back from dating men has been the fear of freaking out her children Kylie and Kendall. 

The transgender star admitted she can't see herself dating women in her future, and added 'Yeah I would date a man - and it's kind of nice to get that off your chest.'
