Most Helpful Girl
Having someone outside of your family who loves you for who you are.
Most Helpful Guy
you're secured (assuming you are with someone for a long term thing) you can focus on work or studies for the next few years knowing you've got a girl by your side, you dont have to go out looking for a girl to date and be with, relationship wise you are set.
and of course the opposite gender is always fun and exciting to be around, interesting and attractive as well, you get to talk to her, share things with her and basically enjoy life i guess.0
