This MC is clearly not the typical AVN "ladykiller", but rather introverted and i'd dare to say, a quite decent human being as a whole. Definitely a monogamist (like Vidal

). And this was the choice of the game supporters and fans on the F95 from the beginning. Just look at the "uproar" after the early nude scene of Emma that was considered too early and unbecoming for a respectable bodyguard to react the way he did there.
Emma is just way too immature, also too young for the MC and Charlie too scarred by her past experience. Suzi has been disregarded too long and this is what DB was planning to mend. So no, I don't think so, regarding the in-game time that has passed since the hiring of the MC.
Lucy's path could have been developing faster, but considering how busy the MC has been protecting Emma and Charlie and how little time they have had for each other, trying to keep their relationship a secret for as long as it has been, also no.
Too bad for the "blueballing" haters, this is the story where the MC has to keep it in his pants.
