Should I break up with my girlfriend because of her tattoo?

I have been dating my girlfriend for about 3 years now and about 4 months ago she got a tattoo of her deceased mothers name and a little saying under it on her upper chest. Everytime we have sex it seems to really bother and sometimes she wants me to ejaculate on her face or chest area. Im fine with tattoos but having to look at her deceased mother name while having sex and what not really bothers me but id hate to tell her that. What should I do?
