A man normally wakes up with a hard willy. It is even the signal to get up. It is often thought that the willy becomes hard because the man has to urinate. This is nonsense.
Peeing with a hard willy is very difficult. The bladder automatically closes correctly because there may be an orgasm. In addition, the prostate may be somewhat swollen when standing up, which makes it extra difficult to pee. It is precisely this prostate that is located between the bladder and the penis.
The video above shows how difficult it is to pee with a stiff willy. The guy really needs to press force it. It only works a little bit at a time.
From the prehistoric times and all the danger in that time, the morning is a safe moment for sex (all dangerous animals are sleeping). But also a difficult moment for a man, because he has been sleeping all night and the bladder is full. Every healthy man with a healthy willy wakes up with a hard penis. And every man knows how difficult it can be to pee in between. Especially when it is also a good time to have sex. With themselves or with someone else. A man on his own sometimes jerks himself off first, so that peeing is easier afterwards.
However, it is absolutely no sign that his willy is so happy with who is next to him. It simply always happens. First to awake is always a man’s willy. And then him. This is often still embarrassing among men. While it’s just his same willy. But then hard.
