Is massage and nude beaches cheating?

I am in a long term relationship and I would never cheat on my guy but I really long for the touch of another man and to be looked at by other men. I like to get massages because I like to feel another man rubbing my body, I like to do naughty chat because I like to talk dirty with another man every so often, I like to go to nude beaches so other men can see my boobs….is this wrong? I want to be with him forever, but every so often you need a little variety. Men get to show their bulges to women other than the ones they’re with everyday so they can cheat in a cheap and harmless way, why can’t girls be a little slutty without actually having sex outside of the relationship?
