Condoms* and female condoms are the only forms of contraception that protect against STIs. They are available in different sizes, flavours and types, and some can be used to help delay a man's orgasm or increase pleasure for both of you.
It's easy to use a condom properly. Always carry condoms in a tin or condom case rather than your wallet or bag, as otherwise you could damage them. Read the condom pack instructions and check the expiry date.
Either partner can put the condom on but wash your hands first: this helps keep things hygienic and, if you've been playing with massage oil or anything else fatty (ice cream...?) it removes oils that might otherwise cause the condom to break.
Put the condom on before you get down to it, so you can writhe away safely to your heart's content during foreplay (don't wait too long though – you don't want the condom to dry out).
Tear the wrapper open from the serrated edge. Watch out for fingernails, teeth and sharp objects like jewellery and body piercings – you don't want to tear / rip the condom.
Check the roll is on the outside: otherwise it'll be inside out. If you're unsure, blow lightly into the condom and it will unroll slightly, making it easier to spot which way is the right way round.
Squeeze the condom teat so there's no air trapped inside, and, still squeezing the teat, put the condom on the top of the penis and roll it down with your other hand.
If you feel it start to roll back up during sex, roll it down again immediately. If it comes off, stop what you're doing, pull it out by the open end and put a new condom on.
Once the man comes, and while the penis is still erect, hold the condom by the base and withdraw. Then take it off, knot it, wrap it in a tissue and throw it in the bin (not down the toilet – think of the planet) Never re-use a condom: if you think you're in for a long night, go adequately equipped.
