I tend not to tell hubby when I'm ovulating, instead just BD every other day all cycle, that way I know I won't miss any days.
We were chatting about this the other week in another thread, about mixing it up too to keep it interesting. It was the reverse cowgirl that got me the bfp before this one! I think Hubby forgets we're baby making at that point, and just gets, erm... ahem, stuck in!!
