Tattoos don't bother me personally, although I have never had one myself. So I would not be trying to cancel a contract for that reason, it would be ridiculous.
I still don't get it, you say the tattoo is for yourself. Is it a memento of a special event in your life, artistic expression, or a badge of honor that you can bear pain?
IIRC I have said before on this thread having a tattoo does tend to act as a socio-economic classifier, which is probably the reason I don't have one. Although I have met some with tattoos who were good people.
