Is getting a massage considered cheating?

No, its not cheating at all but put yourself in her shoes and imagine how you would feel if you found out. She's going to think your lying because you never told her. Why not ask her for a massage instead? Or better yet, give them to each other. Massages can be great foreplay.

Going by your other Qs, you're getting massages from somewhere not totally legit and trying to solicit 'happy endings'. Yes, that's cheating.

you are keeping something from your fiance

so its lying by default

ask fiance to give you a massage

she like many females wont relish someone else rubbing their hands all over her man

she will be a willing participant, and you will probably get a happy ending

win win

No but why are you afraid to tell her about it? If she ever found out it wouldn't look that great simply for the fact that you've been hiding it.

Absolutely not,you're just treating yourself after a hard days work which you clearly deserve,you shouldn't feel guilty what so ever and if she complained about it i'd be shocked.

No

if its not your genitals
