I did do alot of research about popping and watched numerous video in the popping technique and waited till i was confident i wouldnt hurt my snake .did it myself and came to the conclusion that she was a female based on pics of both sexes when popped,obviously she survived me,and i didnt try it again and just went with the results.allthough i will always have doubt about my diagnosis.so its either wait and see just how big she gets or spend the money and clear my concious..anyway thanks again to all
