Kissing seems like a big deal to us when we're teenagers, but as we grow older, it can start to lose a little of its mystique. It's a great shame because it's a wonderful way to build intimacy between partners, and without it, sex can start to feel a little impersonal.
In a fetish context, there are plenty of ways to make kissing a part of your dynamic. Kissing someone who is tied up can add to the sensual feeling of helplessness, for example, while kissing a blindfolded person all over their body will keep them wanting more and make them unsure what to expect. It can also form an important part of aftercare, helping you to reconnect with your partner on a cosier level after an encounter that may have been quite emotionally intense.
