Waiting till I'm ready

So right now my SO and I are both 17 and going to be juniors. We both are virgins to sex and have only don't sexual thugs with each other. For a while I had trouble deciding wether or not I wanted to do something but have always decided not too. As a kid I was like I'll only have it after marriage but as I grew older I decided only when I feel like it's the right time and I really want too. I've had moments where I've wanted to but I know I'm not ready yet, I'm just glad I have a man who understands and is supportive. He's the best I could ask for and I just wanted to share and see what others think about this too. (Btw we are both Geninis and if it really matters I'm like a week and a day older lol)
