From the Mantis page-

'' “Even though it is their first time, they will be completely unconcerned, and lower their hips with indifference… Upon experiencing intense pleasure for the first time,… After that, they do not just live to survive. They start to live for the sake of living together with their man and having sex.” ''

 Seems like a pretty clear case of a Monster marrying the man they lost their virginity to. Most monsters seemed to me like this, marrying the first man they happen to snag.

 As for them deciding on their Husband before sex, there are monsters who decide to marry their childhood friends, as stated in the Yuki-Onna and Kappa. Also Lizardmen and Salamanders courting rituals regards personal combat not sex, but its stated they will pursue the man they like until he finally relents. Not to mention we have most of the Fallen Maidens who had an interest in Elt before becoming monsters.

 Also its stated in the info section of Monster Girls that a Monsters husband isn't decided on sex alone, their instincts can recognize a man as their husband before ever having sex.
