After kids come into the picture, it may take some creativity and effort to keep the passion in your marriage. One of the things that you can do is to continue to grow as a person personally and sexually. And one of the ways you can do that is to change things up in your sexual relationship, so rather than doing the same old routine you and your partner are used to, surprise your partner with something new. But even better, surprise yourself so that when you look at yourself, you say wow, I can´t believe I did that. That´s something new I have never done before. Next thing would be to keep passion alive is to not take yourself too seriously. You don´t have to be the perfect sexual partner nor does your spouse or partner. And you guys can have fun and be silly and do aventurous things together in the bedroom.
