Yes, I agree with Kim regarding the infection, but also my doctor told me that after my DNC I should have no sex or orgasms for 2 weeks.
An orgasm causes the vaginal walls to contract, which can affect the healing process.
if your the one getting the oral...i would say not do it. because they say not to have sex after a DNC for a couple of weeks maybe 2 or something because of the risk of infection. i mean its not like the person preforming it on you will be licking something dirty but you never really kno whats on peoples toungs and mouths and i just wouldnt want the risk of infection.
