1) It's OK to go to bed angry.
Sleeping it off can help de-escalate the situation and give you time to take on a different perspective. This helps you both to reconcile your differences and compromise.
2) Checking people out together can be good.
Ladies and gents we all have admired the opposite sex at one point or another hoping our partner didn't notice, right? ^__^ Doing this together can build sexual intimacy. It's tricky, but with open communication it can work.
2) Share your dreams/fantasies with one another.
3)Take time apart to spend with your own set of friends.
Being in a committed relationship does not mean you are glued to the hip. Having an individual sense of yourself keeps you grounded and upholds your boundaries when you are in a relationship.
4)Continue to flirt and court each other.
We girls love attention and hearing sweet things about ourselves. I know you guys love feeling like your girl is still so into you. Don't stop just because you are in a committed relationship. Keep chasing and tantalizing each other.
