Using a condom is a good idea to help prevent both STDs and pregnancies, but it is not 100%...as you would know.
I think the pill you are talking about is the Morning After pill, also known as Emergency Contraception. It is supposed to be taken in emergencies only, such as when a condom breaks, etc.. It is only effective up to 72 hours after having unprotected sex. It cannot effectively be used as a form of birth control.
I would suggest your friend going on daily oral contraceptives (i.e. 'the pill'). These are very effective in preventing pregnancies when taken correctly (over 99% effective).
I'm not familiar with porn, but do they use condoms? If not, I don't suggest you follow their example. What you are talking about, I think, is the 'pull out' method. You can still cause a pregnancy even if you are not to ejaculate inside... there may be some pre-ejaculate, which can contain sperm.
If you use condoms you are fairly safe.. if you use them correctly. But I strongly suggest she goes on the pill, just incase. |
