It depends on my cycle... Here's how it pretty much breaks down...
When AF is here- not very much although DH seems to want it more than ever this week, maybe 1 or 2 times (depending on AF's stay)
Waiting to O- probably about 2-3 times... Since DH works nights, I like to let him get his rest to get ready for O time
O time- we try to do it every other day so probably 4-5 times (now that he's back to giving his 200%

)
After O- whenever we feel like it- probably 3 times a week
Now you can all go and laugh about how I broke that down!

I know I'm calling myself a big old Dork right now!
