Is it too serious for high school?


Okay, so my boyfriend and I have been dating for nearly 3 years now (since grade 9 and it will be 3 years at the beginning of December). We are each others firsts on everything from kissing, to relationships, to being sexual in any way. We want to sleep at each others houses (in a non sexual way), but I highly doubt either of our parents will approve even though both sets are supportive and aware of us being sexually active. My question is, is sleeping with each other non sexually moving too fast for a high school relationship? I feel like people are more willing to accept teenagers having sex than they are of teenagers in serious relationships. Oh, he is 17 and I just turned 18 by the way (it is legal and if you wish to disagree I can and will show you the facts that prove it's legal). We are both grade 12.
