I have always told people that what will make a relationship lasts forever is not only in the number of sweet words you say to one another; at times, when you touch your partner, and you hold them very close, a feeling of deep intimacy will start growing.
Deep intimacy is needed between two partners because that is the only thing that will make you feel incomplete without them; you'll always want them by your side. I have read, and I have heard from people saying when two partners cuddle a lot, it makes them feel better and happier.
It will interest you to know that a lot of women prefer cuddling to sex. Sex is just for a limited time, but you can embrace your partner affectionately and stay like that for several hours, especially during the cold period. When you cuddle your wife, you can go deeper by kissing her, and you can equally run your hands on her skin.
