It's impossible without surgery. But I can mention some Asian traits: Skinny Straight hair Pale skin Eyebrows like this img3.wikia.nocookie.net/.../...e-4-wallpaper-1.jpg But I strongly recommend you to stay just as you are. A perfect guy would like you the way you are without any modifications.
That's not healthy for anyone to want to change who they are just for someone else. Your boy-hole should like you for who you are. If he doesn't, then spread his cheeks and fuck him in the hole the shit out.
Why would you want to look more like Asian :/ there is a reason why he chose you as his girlfriend!!
Like some Asian girls love hollywood cerebrities and prefer black or white men but that doesn't mean they would only meet and like black or white men in real life I think i would be maybe little flattered if he likes me over his preference... Like even if he prefers other race or other type of appearance that i dont have... if he still likes me.. Lol I don't know maybe i'm too optimistic to see things only in a positive way 😅🙊 but i really think you do not have to look more Asian
