It really depends on me. At the moment it is the last thing I feel like doing so I really have to make myself "give it up" once a week
DH is ready to go at anytime anyplace the horny buggar he is and he is a shift worker who does 12 hour shifts but is always up for it.

When not breastfeeding, hormonal or feeling gross,fat and wobbly then its usually about 4-5 times a week.
We havent really tried properly to conceive before, just not done anything to stop it so the amount of times is the same.
