The size of a condom is utterly important to give protection to both partners by lessening the risks of STD infection and unplanned pregnancy. Wearing ill-fit condoms can increase the possibility of experiencing breakage or slippage during sexual intercourse.
If the size is too loose, it is more likely to slip. Conversely, if the condom is too tight, this can cause for it to break.
Additionally, a snugly fit condom does not diminish sensitivity; thus, the experience becomes more pleasurable. It also gives a better feeling to the person using it, especially if it is lubricated.
