<s>[INST] Hi I m just wondering about sex. I am 16 years old and my boyfriend and I have been having sex but we were recently told that condoms only work around 95% of the time. The contraceptive pill made me sick so we have only been using a condom. I m scared because 5% seems a lot and I don t want to get pregnant. We have stopped having sex because we are so worried. Please help. [/INST] Hallow Dear, Condoms are very successful devices in avoiding the pregnancies if used properly. There failure is mainly due to:1. Rupture of the tit of condom after ejaculation. This happens if the tit is not pinched to remove air in it while putting on condom. Use of outdated condom or repeated use of the same condom also can lead to rupture.2. Failure to completely cover the penis. 3. Forceful pulling out of the penis from vagina after completion of intercourse. After completing intercourse, the girl should abduct her thighs and then let the penis slip off the vagina of its own. When such care is taken, condom is very good contraceptive device. And finally baby, there is nothing 100% foolproof in this world. Every step in the life is with calculated risk. I hope this clarifies your dilemma. If so, you may baste "Helpful vote" to this advice.  </s>
