In the following letter we see a teenage Laurens from his father's point of view.

Master Jack is too closely wedded to his studies to think about any of the Miss Nanny’s

-This pretty much translates to: "He doesn't have any interest in the women around him".

I would not have such a sound in his Ear, for a Crown; why drive the poor Dog, to what Nature will irresistably prompt him to be plagued with in all probability much too soon.

-In this section we see that Laurens' father believes him to be a sort of "late bloomer" and that he will definitely want to have sex with women soon.

This can be summarized by stating "As a teenager John Laurens was disinterested in women".
