You know, this take on Zhao Yunlan rings very true to me. Though just as with Shen Wei, not having had sex doesn't mean he doesn't have a vivid kinky imagination. *g*

It wouldn't surprise me if there was a lot of bonding sex happening in the fighting units.

That also makes sense to me! Actually, I think that's the only context I can imagine pre-Kunlun Shen Wei having had sex at all. As you put it - I feel like he just never had the headspace for anything else.
