Just like any other "item of clothing" the condom comes in different sizes from the narrow to the extra-large, the trick is to choose the right size for the job. If it is too small, the condom is difficult to place on the erect penis. The latex stretches and there is a greater danger it may break. It will feel very tight on you and it will be very uncomfortable. If it is too big, then the condom risks getting folds in it. Worse still, the condom might slip off during sex. The pleasure will be less intense for the man too.
A condom of the right size rolls on easily with the thumb and index finger. Not too tight, not too big, the latex correctly takes on the shape of the erect penis and provides the awaited pleasure.
Each brand of condom has its own standards and characteristics, whether in length, diameter or even ergonomics. It is recommended trying several to find the right "shoe for your foot".
