Okay so it's been like 15 years since I saw half of this movie, always wanted to see the whole thing. I can remember a few tidbits.
1: The main character is a 20 something kind of nerdy boy. There is a scene where he is losing his virginity with a pretty girl. He's kissing her constantly and she says something like 'You don't have to keep kissing me the whole time, you can just look into my eyes'
2: The main character narrates a voiceover where he says he finally understands why people are so obsessed with sex. Something about, when you are doing it... you and seeing how much the girl is enjoying it, you feel like you're the best in the world
3: Another scene he decides the best way to live is to become 'all things to all people' He decides (I think) to impress his dad by being an ambitious business type guy, and make his hippie mom happy by smoking weed and listening to records. (pretty sure his parents were divorced)
That's all I can really remember, it was a slice of life philosophical kind of movie heavily narrated by the main character. I've tried searching quotes and stuff about the scenes I remembered once in a while over the years but could never find it.
