@Yuukir yes? Hasn't that already been established? Early on they said that the priest was currently the only man in the party, and then the hero decided to sleep in a "the womens room" rather than share rooms based on number of beds. And this chapter the higher-up made it very clear the priest is the sole male, suggesting him to seduce all three in the phonecall.
What I find more in question, is whether she (the hero) is scared of men, her reaction when touched was rather big. Might just be afraid of physical contact in general tho.
