Know Your Body, Love Your Body
The better you know your body, the more pleasure it can give you. But while most men get intimately acquainted with themselves at an early age, a more academic study of the area can also prove useful. Get to know your penis and you'll be far more equipped to handle it.
This is the main part of the penis, and swells when a guy gets turned on. Men may worry it's too short, thin or otherwise lacking but generally speaking, men are far more hung up on penissize than women are, and there are advantages to having a penis of any size.
If it's curved, do visit a doctor to check there's nothing wrong as curvature can be caused by certain disorders (or damaged during rough sex but you're highly likely to notice if that happens). However, many men have a slight natural curve to the penis which is nothing to worry about - and can even make it easier to hit the G-spot.
Often referred to as the head of the penis, this is generally the most sensitive part. The coronal ridge (around the bottom of the glans) and frenulum ('string' that runs from the glans to the shaft) are often particularly sensitive and, as such, are great to focus on to give maximum pleasure, and best avoided if premature ejaculation is an issue.
The glans swells and darkens during arousal, as it fills with blood. Some men have a full glans (sometimes referred to as a mushroom head). This can make some condoms uncomfortable, but Durex has created condoms tailored to suit men's natural shape to get around this problem.

The Urethral Meatus
This is the tube through which ejaculate shoots during orgasm. While some men get pleasure having it stimulated, others find it far too intense, so handle with care. Sliding anything down the urethral meatus is not advised as it can get stuck, and you don't want to end up in hospital.
Some men have their foreskin removed for religious or health reasons (for example, if it's too tight - there is little evidence to suggest removing the foreskin is healthier on a general basis). The foreskin helps protect the glans and also helps the penis self-lubricate. As such, if a guy's had his removed, you'll probably need to use a lot more lube during manual play.
