This girl asked me for help and I agreed to because I'm hoping to get in her pants.
Are you serious? Hypothetical sex is the only reason you helped her?
Yes, but I did a lot of things to help her. For example, I did a lot of favors for her and tried to have a proper conversation with her.
You seem desperate if you're just hoping she'll throw some sex your way. I think you need to readjust your moral compass because helping someone in hopes for sex just isn't right.
There's nothing wrong with trying to have sex with someone.
It is indeed perfectly normal to want to have sex with someone, but it's not right to help someone solely in the hopes that they will reward you with sex. You are viewing her as a sexual object which is not right. If she found out that's the only reason you are helping her, she would be very upset.
