If you ever want to have sex make sure it is safe and both you and your partner are ready to have sex. Also, make sure you are both at the legal age to have sex or you could get it into a lot of trouble with your parents or the police.
Another way to make sex safe is drinking less alcohol or not drinking at all because, if you are at a party and drink too much alcohol you are not in the right state of mind to give consent and you will probably have sex without even knowing about it. this can lead to unexpected pregnancy or an STI.
Also, another way of making sex safe for you and your partner is by using a condom as this can reduce the risks of both you and your partner getting an STI or getting your partner pregnant.
Another way and contraceptive to make sex safer are by using a contraceptive pill which 100% of the time will not make a girl pregnant even if sperm is been ejaculated into the vagina.
These contraceptives work most of the time but are not always 100% besides the contraceptive pill. For Example, the condom is only a 98% protection from STIs and pregnancy.
The last way to keep sex safe or safer is by not having sex at all or no sexual contact.
