Roll not push, you roll the hemipenes out

Sounds a lot like 2 males fighting, although some strong males will fight with a female if she's trying to hold him down, it rarely lasts for more than a few seconds of tussling.

I would practice popping sub adult males, it won't hurt them for you to pop them several times a week practicing, especially if you are rolling out the hemipenes instead of pushing them out.

Good luck, I hope she is a "she"
