Are males always that rough?

[Up_North]

First time breeder! Waited for fems. to grow big and fat and today I put my male in with one of the girls I felt was ready inbetween 40-50g as soon as I put him in he walked around then he saw her, chased her down grabed her tail and draged her to the midle of the encloser where he bit her leg and neck and had his way with her!!! Didnt seem very nice to me! Is this normale breeding behaver or was my poor girl raped by a man handling, fem. mauling monster of a male?
