If she is not confortable then she is not and it should not be expected of her to be comfortable with you going somewhere else to get your kicks. We don't always get what we want, but we deal with it.
As this is something sexual for you, going away from her is cheating on her.
Thanks. I think that after this 30 day tribulation , the more important question is if she can be flexible with my fetish or not be surprised if I go looking for it elsewhere, or be married and let me have my own foot massage service that way she knows I'm not cheating on her and I can enjoy what I truly like.
Sorry about my spelling and grammar. I'm typing from my iPhone at work and trying to be discreet too.
