Caitlyn Jenner is done dating women.
In the season 2 trailer for "I Am Cait" she flat out says it ... "To be honest I don't see myself dating women in the future."

Up to this point, Cait's been very coy about her dating life -- and she's been on the fence about whether she supports same sex marriages. So maybe she's tipping her hand by deciding to date men.
One other option? It's all BS ... since this is a promo and nobody gives promo like a Jenner/Kardashian.
