Off course its cheating. Be it a massage with a "happy ending",touching & mutual masturbation,oral sex or penetration,the sin is equal. You are sneaking around and doing it without your partner knowing about it,so you are cheating.
Paying for it or not,it does not make a difference, its still cheating.
