This question was posted at the Law and Legal Issues site, if you're asking when is a girl physically and emotionally ready for a sexual relationship - you should post the question elsewhere.
Under the law, an under-aged girl in a sexual relationship may be adjudicated delinquent. The age will differ from state to state but in most states it's 15 or 16. The person having sex with an under-aged girl may be guilty of "statutory rape" which is a felony. Rape of an adult means forcing the adult to have sex against their will by force, threats or trickery. Statutory rape means the girl consented to the sex, the girl may have even initiated the sex and seduced her partner, it's rape because she's not old enough to give consent under the law.
it isn't but it should be illegal
as long as their relationship does not involve a sexual relationship otherwise, you should check the laws in your area to see if it is legal
The type of relationship between a young girl and the old man is sexual offense of age.
Depends on how old you both are. If either of you are 15 or under, no relationship should be considered "serious." If you are older, then it doesn't matter how many relationships she has been in, you have to start somewhere.
A 13 year old girl should go out with an 19 year old long as it is okay with the 13 year old girl. If shes not okay with it than they should report it to the police right away.Another is long if there their both not sexually active than the relationship should be okay. Although the relationship probley won't work out. After all the 13 year old do have to wait for a lot of things to come towards her.
It is completely your and the girl's choice if you are going to date, though personally I think that no matter how mature you think you are, you are probably not ready to enter into a relationship at your current age. Be a kid while you still can!
No.
If you both expect the same of your relationship, there is no real disadvantage.
Get married when you are both sure that the relationship will last.
.Can we start by learning the nature of your relationship with the 13 year old girl in question?
Tell her how you feel. Find a private moment when your alone with her, and just blurt it out. If your old enough, and she recipricates, you can start an enjoyable relationship.
Helll Yeahhh !!
