“Don't knock masturbation. It's sex with someone you love.”

“Love doesn't have limits, and you don't make love with someone's sex-you make love with a person.”

“You don't just decide to have sex because you feel like having sex. You decide to have sex once you realize you're in love with someone and want to express that love physically.”

“Physics is to math what sex is to masturbation.”

“You don't fall in love with someone because it's convenient.”

“Seizing an imaginary microphone, Dennis adopts a limp Estuary accent: 'Masturbating's changed a lot since I were a lad, Brian. In my day, we masturbated for the sheer love of it. Day and night we did it, all the kids on our estate, masturbating on the old waste ground, masturbating up against the wall of the house... I remember me mam coming out and shouting, "Stop that masturbating and come in for your tea! You'll never amount to anything if all you think about is masturbating!" Masturbating crazy we were. Your young masturbators today, though, it's all about the money, it's all about agents and endorsements. Sometimes I worry that the masturbating's in danger of being squeezed out altogether.”
