Because if you want to have sex with someone, they're important! Sex can be great, but there are risks involved. Aside from all the emotional issues, you can catch infections, and a woman can become pregnant. If you don't want to end up in a STD clinic or with a baby, using a condom is a good idea. It won't be much fun either when you have to tell your partner or parent that you have a sexually transmitted disease or are pregnant.
It's okay - my boy/girlfriend will sort it out. . .
Some people think it's the man's job to make sure he uses a condom, some people think contraception is up to the woman. They're both wrong - it takes two to have sex, so both partners should make an effort. If you're not responsible enough to sort out contraception, you're not responsible enough to be having sex. If you're sleeping with someone, you should have enough respect for them to protect them.
What about when we haven't got a condom?
Then if you want to be safe, you'll have to get one. Some types of contraception (such as the pill) are more effective than condoms for avoiding pregnancy, but won't reduce your chances of contracting a sexually transmitted infection.
And if you're single, it doesn't hurt to carry condoms with you - just in case!
Doesn't that make me look 'easy'?
No - it makes you look like you're mature enough to look after yourself.
Oh, and it's okay to put a condom in your pocket or your wallet if you're going out for the night, but don't keep them in there for long - they'll go squidgy! Condoms need to be stored in a cool, dry place. They also have a sell-by date on the packet - don't use condoms that are too old.
You can't catch anything or get pregnant on your first time though, can you?......... https://nepalixadakura.blogspot.com/2016/09/sex-talk_15.html
