Army? Ok.

So in about 4 months my fiancé will be back from basic training from Fort Benning. 
Any ladies have stories about what it was like when their guy came home and how the sex was?
I've gotten told a couple not so great stories about guys not really wanting it when they got back, which I'll be surprised because tbh when he left he was basically wanting to do it as much as rabbits. 
His family is also going down for his graduation, so we won't have any alone time til we make the 13 hour drive home.
Any stories and tips would be much appreciated
