Is it normal to have a friend who always acts like they are perfect?

I understand what you mean. Its not like you're necessariy jealous, it just can get obnoxious after a while how pretentious they are, and how perfect they try to make themselves out to be.

But maybe you're better in certain areas that he actually sucks in. You just don't know it yet, because you guys haven't touched on it yet. You've been too busy listening to the things that he's good at. Like, when you say that he hooks up with a lot of girls... so maybe he has a knack at getting the ladies..., but you're better in other areas.

Anyway, don't let it make you feel shitty. Theres actually a lot of people like that in the world.

Most people - especially in school - are like that.

First you should ask yourself why you are feeling what you are feeling.
Second, just maybe they are just being who they know how to be. Why not choose one that you think you may be able to have a conversation with and explain your feelings. Often people are so unaware of other people's feelings until someone says something.
Given these points, if all above does not unlock your question, maybe you need to find new friends. Remember, not all friends are meant to be in our lives forever, and some are. It is up to you to figure out do they still fit in your life.

You might just be a bit jealous.

@Erick963 I agree.

Yes, OFC, it's normal to be irritated at a situation like that. IMO I just think that he is being himself and that he's not really trying to outsmart you. You can either move on if you think he is trying to be a showoff and act more better than you, and find new friends. Anyway, TBH, really it's GREAT to have a friend that is really outgoing like that and knows a lot of things. He can teach you valuable lessons about life and about the world. You say he knows much more than you, right? Then he can help you get into a good school, life, and everything else. Plus, don't depend on him all your life because he's probably not going to be there for you all his life, because he has to live out on his own and he has still yet many things to discover. Just because he has had a greater, nicer, better life and he actually studied A LOT to get to such a good school doesn't mean you should be annoyed by him a lot. IMO People that tend to have a lot of awesome things and things heading for them in life might show off a bit and tend to outsmart others. Just tell him if it's annoying you and he'll cut off it a bit. Just remember you shouldn't control his life, and he shouldn't control yours. If you're really annoyed by him just hang out with other friends.

BTW, all in all of the best, I do agree with Erik963.
"It is never who is better in what, it is about how you enjoy to hang out, or if he helps you in creepy situations." Be such a friend you can be and just be nice to him when he outsmarts or annoys you like that. Just because he gets better girlfriends or whatever or knows much better than you doesn't mean you can't! Focus on what YOU want in life, not all up in his life. You are NOT responsible for what happens to him, or what decisions he makes. You, as a friend, are only there to help him and be loyal. (: Good Luck.

It is normal to be annoying about such a thing. There is nothing wrong with it. My best friends acts almost same, but I mostly do not take him seriously and make fun of this and than we both end up in laughter.

It is never about who is better in what, it is about how you enjoy to hang out, or if he helps you in creepy situations.
