It’s perfectly normal for young people to have strong physical needs, but I hope everyone doesn’t lose their ability to perceive pure, innocent feelings. Whatever you do, don’t just fast-forward straight to the doi stage—if you’ve had too much of that, you’ll find it’s tasteless to consume and a pity to discard; it’s all loneliness. The more people you sleep with, the higher your threshold becomes, and later it’ll only get harder and harder to truly like someone. More terrifying than physiological erectile dysfunction is psychological erectile dysfunction.
