Sounds to me like a, "
Prove that you love me" challenge by an insecure girl. Especially, when they both claim to want to withhold sex for a few years.
Does this girl feel if Vrai "comes out", they'll be able to "pet" in front of Vrai's parents? Vrai said this girl has "come out" to her parents, IIRC, yet they worry about being caught "petting" at her house.
I wouldn't be forced, coerced or pressured by this girl. I see no benefit to you and possibly some harm by taking a position at this point.
Like elspode said, the guys would be all over you, and if you think this girl's pressuring you, well you ain't seen nuthin yet. Of course you might be able to convince your folks that coming out is a ploy to attract the boys. Remember coming out is a declaration of your sexual preference and everyone (including parents) will assume you have to be sexually active to make that choice.
I'm rambling...uh, thinking out loud.
Bottom line ....don't do it.
