In my experience with drinking beer, forcing yourself to drink it so you'll like it is not the best way to go. If you really want to see if you like beer, see if you can find some place that does tasting flights. This is a good way to try small amounts of many different beers to see if you can find something you actually enjoy. I don't know where you are located but a bar near me called World of Beer (which is a chain) will generally let you sample things before you buy a glass. Many other bars that specialize in a wide selection of beers will often do the same. Another option is to visit breweries if there are any near you as they often will have tasting samples at the end.

Lastly, you shouldn't feel pressured to like beer just because others do. If it's not for you, it's not for you. I know some people who just absolutely can't stand beer, and that is totally ok. You should drink what you like, not what other people expect you to drink.

Good luck with finding something you like and remember, if you don't like beer, that's ok!
