True, but I find it very unlikely that the peeps at 343 will ever dare to go farther than a kiss on the cheek, so sex is probably out of the question.

Now that you think about it, Halo canon overall has been pretty devoid of any actual romance (except for hints in Dirt, a short scene in Contact Harvest, the Black-One-Three-Four triangle in Blood Line and possibly Chief & Cortana)
