I think you are doing better than you think. Knowing that you are ready is taking the first step in having sex. I was 18 when I lost my virginity and didn't have a clue what I was doing. But don't feel bad. It takes awhile to know. I'm 24 now, and I feel alot better about myself and am more relaxed about sex, mainly because i am in love with the person that I am having sexual relations with. HAHA Anyway, just relax and try new things, positions and such. But there isn't really anything anyone can tell you to have better sex or be better at it. You really have to be confortable and understanding about each other's bodies and just let things flow naturally, so to speak.
