Recording settings for a sɘxtape

Hello there, I come here because I'm a newbie about sound engineering but we're planning to film a sextape with my girl and I wanted it to have good sounding. I'd like a real deep sound capable of capturing even the breathes, retransposing the ambiance in the room I presently have a zoom h2n, and I was wondering should I use it in XY or MS mode ? Should I use a comp or a limiter ? How much gain typically?

Thanks much for helping creating a real cool vid (:
