I had a heat source to burn away abnormal cervical cells 4 days ago. can i masturbate, or do i have to wait the 4 weeks to resume orgasm activities?

Yes : with many minimally invasive procedures for GYN procedures as well as urological procedures, patients return to their normal activities fairly quickly

Cervical surgery: Abstain from putting anything in the vagina for at least 2 weeks. Hopefully your physician schedule a follow up to make sure no infection. Clitoral stimulation with fingers or vibrator is fine, but again don't put anything inside the vagina (no sex, no toys, no tampons, no douche)
