How long after vaginoplasty can i resume sex?

Depends: Only your surgeon can tell you for certain, because there may be issues unique to you or your procedure, but 6-8 weeks would be a typical waiting period.

Six-8 weeks: I would agree that 6-8 weeks is a reasonable time. I have patients who have had sex at an earlier date but this risks the possiblity of wound breakdown and other problems. Generally speaking most wounds are healed by 6 weeks, a brief period of scar massage, desensitzation therapy and vaginal dilation may be advised prior to resuming sexual intercourse.
