Hi hun, i have only just conquered this at the age of 27.
I didn't have any probs with a smear, i explained to my nurse and she took it really slow. There was a little discomfort but nothing i couldn't cope with, this was actually before i was formally diagnosed.
When i was diagnosed i was given dilators to work with and within a month i was able to enjoy intercourse, have had no problems since.
Have you seen your GP hun? I was referred to the hospital to rule out anything else and my consultant was brilliant, reffered me to a specialist female nurse who helped me overcome this properly. Good luck hun x
