Staying with SO for the first time?

Me and my boyfriend have never spent a night over together, but in a few days, I’m staying over at his house with his family for a week. Any advice? Sex tips, freshness, how to little the awkwardness, he hasn’t even seen me without makeup! I’m gonna lose it, I’m so nervous! How do I impress his family? How do I stay soft, and clean shaven for a WHOLE WEEK?! Ah!!!
