Is dating a 17 year old when your 19 illegal

I assume that's what you mean, when you ask what you "can and can't do."

Sexual contact is sexual contact, even if tab A doesn't go into slot B. Oregon law - like the wisest writers on sexuality - doesn't recognize a distinction here. 'Sex.' in this context, by the way, refers to all sexual contact, not just intercourse. Normally, it is against the law in Oregon to have sex with anyone who is under age 18. (If you think that dating someone is just the same thing as having sex with them, then you are too young to be dating.) But there are laws governing who you can have sex with. First of all, there are no laws governing who you can date.
