I can’t remember this movie, it’s driving me crazy. Please help!

I watched a movie a few years ago, it wasn’t new then. It was about high schoolers and their parents. The main teen guy character likes a cheerleader and when he finally get her to his room, he can’t “perform” because he has watched too much porn. His father was played by a well known actor and he also watched porn. A girl has a crush on a guy playing video games, maybe with her brother or friend. She decides to have sex with him and after he just goes back to playing video games like nothing happened. I think there is another girl that is pregnant in the movie or could be the girl I just mentioned gets pregnant. What is this movie???
