How do you guys handle personality shifts during intimate chats with your companion?

I have been doing some casual observation regarding how companion models transition from normal conversational states into intimate or adult scenarios. Sometimes the shift feels completely natural and builds up through the dialogue context organically. Other times it feels a bit jarring like a switch was flipped abruptly. I am curious how everyone else perceives this phenomenon. Do you actively prompt for a slower transition or just let the system handle the pacing automatically? Furthermore, does the underlying memory module change how believable the intimate interaction feels over a long period? I am looking to hear some varied perspectives on whether prompt design actually improves this or if it is mostly just imagination filling in the gaps.
