I can understand your hesitation. Cultural mindsets are very strong, and they color everythig in a person's thought and emotional life. Whereas in a culture like the United States and Brittain, where personal freedoms and independence are highly valued, in other cultures having family and social approval and conformity is held in the upmost place of importance. Love will be birthed and defined by how well people can accomodate their lives to those situations. So to say that he does or does not love you may depend entirely in how well you fit into his culture's definition of what a good partner is.
Perhaps he may be one of the individuals who has come to the US or was born here who has drifted away from his own cultural traditions and is more accepting of the traditions here. If so, then he is more likely to be open minded and accepting of something that traditionally would be taboo. However keep in mind that cultural traditions go very deep into the psyche of human beings, and no matter how far a young person goes away from them, as they age they will usually go back to the teachings of their youth.
In your case, like Melissa I'm much more concerned with his anger and narrow mindedness than anything else. I can understand cultural differences, but aggression is not a good thing to bring to the table no matter what.
It would not be surprising if his response is not all accepting, and it is not to be viewed as an indication that he does not appreciate you as a person, but in a culture where a woman's purity is highly valued, this may be very hard for him to accept. Even though you say that you acquired it at birth, there may still be some stigma attached for him. If he is recoiled by the situation, then it's just one sign that there would be many other areas later on where the disagreements would run rampant. It is these differences that can make intercultural marriages very challenging, and successful marriages of this sort are a wonderful demonstration that true spiritual love can transcend anything, but it is rare.
Approach him very gently but truthfully, and be prepared for both, a positive as well as a negative reaction, then take it from there. I wish you the very best.
