...this post makes me sad, I'm 19 and not only have I never EVER had a girlfriend, I've also never had sex, or been on a date, or even HUGGED a girl who wasn't a member of my immediate family.
*sigh* OT: My thoughts on sex are simple, do it when you feel you are ready, it is a parents job, not to hide it from you, but to prepare you for it, to make sure that you are ready for it when the time comes, people are far too sheltered in todays society, and in all honesty most kids have sex around 16 to 18 years old, most before high school is over for them. What you did was perfectly normal, and the only part that felt truly wrong was when you had unprotected sex and she wasn't a virgin. There could have been some very serious problems from that, and even though a condom isn't 100% sure fire, it is still better than getting an STD and wondering what could have happened if you had used one. Over all this is a fine story, and one you should be proud of. Better than being a total overweight nerd like me who can't even talk to people, let alone a girl.
