How it works

What is inside, how it gets hard and why sometimes it does not, where it feels the most, then precum, orgasm, how long it lasts, how much comes out, what it is made of and the time it takes to go again

What's inside

Three tubes, a valve, a gas and no bone at all

Erection

The hardness scale, morning wood and what happens while you sleep

When it won't go up

Nerves, condoms, chems, porn and the pills that help

Sensitivity

Nerves, hot spots and what dulls them, from age to saddles

Precum

What it is, how much and whether it carries sperm

Orgasm

Coming, step by step: muscles, brain and the prostate

How long it lasts

Stopwatch numbers, coming too fast and what actually helps

Ejaculation

How much, how far and how many spurts: shooters and dribblers

Cum

What it is made of, what the colours mean, and swallowing

Going again

The refractory period, dry orgasms and multiple orgasms in men
