We need to stop our fixation with an orgasm as the be-all and end-all. The more you concentrate on it, the more difficult it will be, so try to enjoy the experience as a whole and appreciate other sensations. Use your first night as a time to get to know each other’s bodies and if you know what you like, guide him in the right direction.
Whatever you do, don’t launch yourself into a fake orgasm to satisfy his ego. You’ll both lose out and will end up feeling empty and frustrated. How do you want things to get any better if he thinks they’re perfect already?
