Male and female virgin couple having sex for the first time-What were your memorable higlights?

At one stage we were all virgins without sexual contact with the opposite sex (or same sex). We were both virgins at the time of our marriage (20+ years ago) and it was our first sexual encounter with another person. We both had to learn each and every aspect of sex on your own. It took us at least 3-4 days before had a successful full penetration. Initially I used to cum within seconds and I was not sure whether my wife ever reached orgasm at all. Now we have learnt a lot and became experts in achieving prolonged pleasures of sexual intercourse.
