Is it supposed to be like that???

Last year I went to the OB-GYN because I thought I had PCOS. I had an ultrasound done. The first part where they run it over your stomach went fine. Then the ultrasound tech tried to do the one that goes inside. Worst. Pain. And. 2 Seconds. Of. My. Life. She barely put it in. She asked if I was sexually active and I said no. I am a virgin, haven't touched myself even, not that I can remember. Then she said the pain was because it wasn't open enough. Over a year later, and I can't even get a Q-Tip in there without discomfort and pain. I tried the Q-Tip earlier today and I didn't tense up, was actually calm. What do I do?
