it Depends on how old but sometimes they try to take advantage
You just do it.
Depends on the guy. Definatly not if the girl is under 18.
Yes, age is not usually a concern, well it is depending upon how young you are because your parents may not agree. But yes a guy two years older would date you, a guy 5 years older would date you it's weather or not you present yourself to the guy in the right way, you need to be yourself and not let things get contradicted cause then things get messy and you'll get hurt, just be honest with yourself and with the people involved, honesty is the key.
no!
It is unless you are close in age.
Your parents can allow you to go out with an older guy. there are no laws against that in any case. but no signature of your parents will make it legal for you to have a sexual relationship with him that would normally be outside the law.
If you are both older than 18 then yes
Normally older but, if its only a year you could date either one.
sure
If he/she wants too, yes.
at school.. 3 years
If your under 16, Its is illegal to date someone 10 years older. This person would be considered a pedophile. And you know, it'll feel a bit weird. Think about it, pretend your 30 and you're dating a guy/woman who's 40.
