Different modes of condom failure result in different levels of semen exposure.

Standard condoms will fit almost any penis, with varying degrees of comfort or risk of slippage. Many condom manufacturers offer “snug” or “magnum” sizes. It is recommended for condoms manufacturers to avoid very thick or very thin condoms, because they are both considered less effective. Some authors encourage users to choose thinner condoms “for greater durability, sensation, and comfort”, but others warn that “the thinner the condom, the smaller the force required to break it”. Experienced condom users are significantly less likely to have a condom slip or break compared to first-time users, although users who experience one slippage or breakage are more likely to suffer a second such failure. An article in Population Reports suggests that education on condom use reduces behaviors that increase the risk of breakage and slippage.

Among people who intend condoms to be their form of birth control, pregnancy may occur when the user has sex without a condom. The person may have run out of condoms, or be traveling and not have a condom with them, or simply dislike the feel of condoms and decide to “take a chance”.

Many men prefer collection condoms to masturbation, and some religions prohibit masturbation entirely.

Condom therapy is sometimes prescribed to infertile couples when the female has high levels of antisperm antibodies.
