joining a fratenity in junior year?

Hi everyone, im a sophomore here at WSU and i was wondering if its a bad idea to join a fraternity in junior year? I did formal this fall, but left formal half way through, due to personal stuff going on back home. I know if i stayed i would be in a fraternity, but during formal i couldn't really concentrate due to my personal life problems at that moment. Anyways back to the present, i have been kinda curious about joining a fraternity or not? there is one that im already in talks with, but i feel like its too late to join. I well be 21 in middle of this fall. i have also been told by my friends (Greek and non Greek)that im going to be 21, so there is no reason joining. Because i can just go to the bars, and that the only girls i well see is little freshmen/sophomore girls at frat parties, which some consider creepy. And that most guys around 21 drop their fraternity anyways. But in the other hand, i would make a connection with other men with same interest and ideas, aka a brotherhood, and it would keep me busy in my free time. Overall im not sure what to do. what do you guys think? what would you do?

P.S. i typed this on my phone, so don't give me the spelling bs.
