Ah okay. Very mature. I think 17 is a quite acceptable age to start, and frankly I love sex. Why should I hide that? It's natural. I was really interested why you'd have a problem with that.
Yeah, I think everyone should sort that out for him-/herself, take as much time as you need. That's why I don't find it quite nice to tell other people to "don't be like" me.
I only started by the end of 17 too ^^
Just wait for someone special and who makes you feel special. You will notice if it feels right for you :)
