1. Tip of the Penis - The foreskin covers the glans. If you do not wash correctly, a white substance gathers, called smegma can be found in your penis. Smegma is a combination of dead cells, skin oils and moisture, and bacteria often thrive in this dark, moist and closed space. So, pull the foreskin back as far as it would go and start washing this area with lukewarm water. Be careful to wash both the glans and inside the foreskin, the part that is not normally exposed.

Make sure you are super clean down there because a man who takes off his shorts revealing an unclean penis is a bigger turn-off to a woman. This can be a big gaffe. Another, you can't expect oral sex to happen if you don't take good care of yourself.

Men who are circumcised have to be just as careful as the non-circumcised guys. The lack of a foreskin means that bacteria and dead cells do not accumulate there and glans is no longer protected from contact with dust, sweat and all sorts of substances and fabrics that would otherwise be kept away from the penis. Some doctors also think that circumcised penises are more exposed to bacteria causing infections of the urinary tract. That is why keeping yourself clean at all times is of paramount importance.

2. Base of the Penis - This is the area that you should focus where where sweat and hair combine to produce a strong smell, just as in your armpit. The area needs frequent washing in order to keep sweat from gathering there since it's covered by underwear for most of the day. Shaving or clipping down the hair is a very good idea particularly in summer. Washing is far easier without a lot of hair getting in the way. Between the glans and the base of the penis you might also want to give the shaft a thorough scrubbing for good measure.

3. The Testicles - Sagging between your legs, the testicles are even more prone to producing an unpleasant smell as sweat can accumulate in the folds of skin or in the space between the penis and the testicles. You should wash each of them carefully and make sure that the small patch of skin between the base of the testicles and the anus (the perineum) is also free of smell and clean.
