Well I waited 5 months to make sure I really know him and that I am comfortable with him. I have been with him for 2 years and 2 months now and at least we took our time. We were both virgins and I was 18 and he was 17 when we first met now I am 21 .
Just don't plan to do have sex, go with the flow. If you plan sometimes you may regret it and you don't want this to happen. Just make sure you are both ready. It just comes naturally when you want to do it. The right moment will come
