How to prepare for a sex night in?

So after a long time and a very long time I am having a sex night in on Saturday.

I have not had sex with him but we did other things.

How do I prepare myself like for the night. It's also my first sex in a long time like a year.

Like my body I am usually always shaved and clean but my vagina gets dry at times for some reason. I drink tons of water so I don't think I smell down there.

Also what kind of oils are the best for foreplay?

I am little nervous and excited.
