What happens if you and your partner have hpv, does that mean you can't have oral sex anymore?

All sex is OK. When one member of a couple has HPV, it can be assumed the other has been repeatedly exposed and probably infected. At that point, there is no need to stop having sex of any kind -- vaginal, anal, oral. Even if you have or get oral HPV, it very rarely leads to cancer or any serious problem of any kind. No worries -- go ahead with unprotected sex of whatever type gives pleasure to both of you.
