I understand your concerns because I am Christian and have dated outside my religion with bad results. If you are accommodating and like to submit to others, then it should not be much of a problem. However, if you are not, issues can arise whether it be about food prohibitions or dress prohibitions etc. I would proceed with caution and be wise about such cultural and religious differences. It does not matter if you are white or black or whatever, such differences can cause much stress in the long run and much problems if you can't understand and accept them.
