How do you make a relationship not boring after dating or being married for how ever long your lover?

have threesomes with different animals

Do some thing that the both of you have never done together. Like a strip club, a clothing optional beach, going to a gun range, or just being spontaneous.

hang out at movies or mall or u can go do dinner

Sex

Errm i guess

if you really love each other, you'd always be happy. You'd always want to make an effort to do something new or enjoyable. Things should never have to "get old."
