Using these condoms alone is not as effective as using a condom along with a separate spermicide. Some pre-planning is needed in order to have a condom handy at the time of intercourse. Since the condom must be put on when the penis is erect, but before contact is made between the penis and vagina, there is usually a brief interruption during foreplay. Many couples solve the problem by incorporating the process of placing the condom on the penis into foreplay. Prevents sperm from contacting the woman's tissue, therefore decreasing chances of her producing antibodies against the sperm.
Condoms have a slight tourniquet effect on the outer veins of the penis.
This may be beneficial for men who have difficulty maintaining an erection. The condom frequently prolongs the man's plateau phase and increases enjoyment for both partners. A few men are unable to maintain an erection after putting on a condom. There is no direct contact between the penis and the vagina. Friction of the condom may diminish clitoral stimulation and reduce lubrication making intercourse less enjoyable or even uncomfortable.
