I cant develop a taste for beer?

Ive been trying all sorts of brands and i simply cannot develop a taste for it. after like 3 sips i feel im going to puke and ive been ''training'' for almost a month now but i cant get used to it. The main reason is i always feel left out when i hang out with my friends and sometimes they dont even want to invite me to parties cause i dont get drunk and go wild like the rest and i dont blame them.. do people just like this stuff naturally or something?
