Am I wrong to have slept with my boyfriend?

No. But be responsible. I did the hard part and told my mom *or guardian* that i was having sex. It was embarrassing. I was 17. But I knew the risks. I got birth control and she talked about condoms too. Earlier is best. Teens have sex. It happens.

You're 16, he's 16? Probably nothing wrong then, who gave you the idea it was wrong?

Well, it was right.

the answer is very simple - of course not!

Definitely not. You trusted him enough to give him your most prized possession and I hope he cherishes that.
