I'd put money down that the plot will later reveal having sex isn't good enough, you have to be in a functioning romantic relationship in order to not explode from DTG. Breaking virginity is only a temporary measure.
This series just gets better and better. The best part is it's so fucking stupid but plays everything completely straight.
@Chrona That's an interesting idea. It does follow from the "sex isn't everything" message the series has been pushing so far. It would be interesting if "players" and other people who have a ton of one-night stands but have never had a real romantic sexual relationship also started dying. You could have scenes were a husband suddenly dies and his wife is shocked to learn he never really loved her.
