eww, no
no because she or he is to young for a 18 year old boyfriend or gilfriend.
There are no laws about dating.
You are both single adults and do as you wish.
Yes. An 18 year old is a legal adult in every jurisdiction, so far as I know. Therefore, an 18 year old could date a 99 year old legally.
Yes your both considered adult age
No because you can go to jail for that because he is older then the age of 18 and you are younger then the age of 18
it is alright but there must be consent from the 17 year olds parents
Yes, as long as the 15 year old turns 16 before the 17 year old turns 18.
No. Until he turns 18, and but with the minors parents permission it is okay.
Tecnically it's not illegal unless they are having sex, but if there not than i guess it's okay!
Yes it is okay if your parents says it's okay and make sure your atleast 18 and older to have sex with that person because if your under 18 it's considered rape.
Sure. It's a problem if anyone under 18 wants sex.
