Pain/cramping during BD

So whenever my DH and I do BD I have cramping and pain. My OBGYN told me that my cervix is pointed downward so essentially my DH is hitting my cervix each thrust (TMI sorry). My question is do any of you experience this and what are your tips. The only time I've not experienced pain is with huge amounts of lube but then I get cramps after so bad that I can't move until the subside.
