It reeks of immaturity in general, or maybe more cynically, the perception of a bunch of nerds that have never had a sex life. There are so few games that handle sexual and romantic relationships realistically, and now that we have one nobody knows what to make of it.

Some characters take things slow. Opening up gradually, sharing some wine, holding hands and enjoying a single kiss on a night alone together. Eventually this ramps up naturally.

Some characters on the other hand are like, "you ready to fuck? I'm ready. Love? Never heard of it."

Both of these are normal and it's cool to see both represented in the same world.
