if your doing anything sexual or with a sexual thought and ur with someone else its cheating. even daydreaming about someone else is a form of cheating in my opinion, even tho that definately wouldnt stop me. i see lapdances and stripclubs like looking at porn, ur doing it cause u find it erotic but with no real bond with the people
one could say u dont have a bond during the massage or if ur with a hooker, but if someone else causes u to bust then ur cheating
