Boyfriend has a Russian/Ukrainian woman fetish? Help? I need a man's perspective about this?

I have been in a serious relationship with my boyfriend for over 2 years. I consider myself to be a relatively attractive young woman: 5'6', green eyes, light brown hair, physically fit. I have had low self esteem issues throughout my life. I try to make myself feel better by exercising regularly and wearing the right clothes and makeup to make myself feel pretty. However, my self image becomes crushed when my boyfriend mentions his thing for Russian women. I am of Irish, French, German, and Gypsy descent, so it's not like I have a Russian background to speak for. Ever since I've been dating my boyfriend, he's mentioned Russian/Ukrainian women several times. Here are some examples:

1. The other day, he and his buddies were talking and he all of a sudden said "Russian women are HOT" (emphasis on the word "hot").

2. He watches Russian women p*rn on a regular basis. I don't mind men watching p*rn by why such a specific genre on a regular basis?

3. He has a 2-year-old sister and his mother isn't sure who the father is. But he assumes the father is Russian because he can tell by her eyes. He said "I think she's Russian because Russian women have that intense blue eye color". Wtf?

4. If we go out shopping for lingerie or sexy clothing, he'll sometimes mention how he wants me to "dress sexy like Russian women." If I wear high heels, he likes how they look Russian.

5. He'll thoroughly check out Russian women on the rare occasion we see one (he can tell by the accent).

6. We're friends on YouTube and he's liked several videos pertaining to Russia.

These are just some examples. His preoccupation with these women is KILLING me. We love and care for each other dearly but I feel that I'm not good enough for him. I can't compete with these women. I'm not Russian and I'm never going to be Russian. How should I address this to him? And should I leave him for a fetish?
