Keep your curfews. Pay very close attention to them. Cradle them, hold them close. The longer you abide by these rules, the more willing your parents might be to extending your curfew as their trust strengthens. The first thing parents will believe if you break curfew is that you're not ready to date. They'll believe you aren't ready for the responsibility or the privilege that dating requires. Prove them wrong.
Typing away on instant message and in chat rooms, reading message boards and posting comments can be very dangerous. Online bullying and sexual predators are two very real dangers you must be wary of. A seemingly harmless conversation can escalate into much more. Do not give out your personal information to people you don't know--even people you think you may know--and do not set up a meeting. One date just isn't worth the risks.
Dating should be fun, but when one person starts pressuring the other to plow forth with experiences she is not comfortable with, it is time to re-evaluate the relationship. Introduce your date to your parents. Start by going on dates in public places, where both parties can relax. It doesn't have to be a long, elaborate dinner and a movie. A date can be whatever you two agree upon. A short stop for coffee could be a date. Remember, a date is really just to break the ice and see if this person is worth your time and interest. On that note, many teenagers believe the cure to a rocky relationship is sex--that he will love her more, that passion will keep them together--but this could not be farther from the truth. Relationships are a two-way street, and both parties have a say. If you don't feel ready for sex, than don't do it.
