Maybe try to find someone to love, rather than looking for a specific race. I get that people are entitled to preferences, but it sounds to me like you're a very sheltered woman, who's only after a white guy because mommy and daddy don't like it. 1. Get a job. 2. Move out. 3. Learn how to take care of yourself, and be your own person. 4. Seek out a boyfriend.
Ok then, 1-3 still apply. If your boyfriend is a grown man still living with his parents, the same applies to him.
Everything is individual, there are white men who want just sex and there are white men who want the deepest forms of love. There are also Asian men who want just sex, and Asian men who want love as well. Think about what you want, then look for the person who will fit you.
I can't remember giving a shit what my parents thought about anyone I was with (or anything I did really) when I was 16 or 17. And lived on my own since I was 18 and surely didn't care about changing my parents opinions of anything.
As a white man I'd like to chip in here and say that if I'm honest, I could envision myself having a relationship that was purely for sex, or one that wasn't purely for sex. In fact that's what's happened in the past. As I get older there's a thought that a once a week fuck relationship might be better than trying to live with someone again.
I do want to say that relationship drama and drama between the genders seems to be universal in all cultures and races. It's only the details of the culture that seem to be different.
