I live in UK so not sure if same rules apply but it is definately considered technically illegal but doctors etc are not allowed to involve police due to doctor-patient confidentiality unless they suspect you were forced or something. I assume you are 13 and pregnant so just talk to your parents if you havent already and relax, if you stress yourself out it will only harm the baby.
It depends on the area the two live in. In the USA, some states have an age of consent of sixteen. So if a 16 year old had sex with a 13 year old, he would be having sex with someone who could not legally consent to sex, so this could possibly be considered statutory rape. Another issue is the age gap between the two people. If it is less than a certain number of years- and, again this differs from state to state- it is not statutory rape. But since both are legally minors, it is debatable as to whether or not anyone would try to prosecute the 16 year old.
"it is debatable as to whether or not anyone would try to prosecute the 16 year old"
There are a number of cases where prosecutions actually took place. Its go a lot to do with what the girl's parents decide to do, press-charges or let it go, and where the sex took place, for example the Jamie Lynn Spears case where she traveled between 2 states to record TV programs. They could not prove where she had sex so neither state prosecuted, even though it was statutory rape in both.
Sad to say but its also got to do with race and local politics.
The unfortunate thing is that the older partner are classified as a sex offender, despite all the fact that it was not actual rape. (I am not saying it is sad when a 30 year old teacher mess with a 15 year old student, only when both parties are of roughly the same age group.)
xxangelxx10, No, it is never ok for you to break the law.
A 16 yo should not be having sex with a 13 yo. There is a massive massive difference in maturity and responsibility between 13 and 16. I know you do not understand that but as soon as you are an adult, you will realize that.
As a matter of fact, a 13 yo should not be having full intercourse yet. There are plenty of time for that and the risk of pregnancy is just too big. She can have all the fun she wants without running the risk of ruining her future. Masturbate or make out like any other 13 yo but keep his penis away from your vagina. If you are willing to see your boyfriend in jail with a sex offender record, keep on doing it.
