Having an orgasm with a man is a very different experience than doing it alone. There's so much more going on. You're thinking about his pleasure. You're experiencing his touch and penetration.
Use your fingers or a vibrator for increased clitoral stimulation during intercourse.
Take his hand and put it where you want it. Then use your hand on his to show him what you like.
Or demonstrate for him on yourself what you want him to do. It's a no-fail guarantee that he will enjoy the show.
If you fake an orgasm...you don't communicate what works....and doesn't work...to your man. Faking...pointless. Showing him what you like...brilliant.
The fastest route to orgasm is often with a good vibrator. A vibrator gives you stronger and more consistent stimulation than your fingers can.Vibrators...
Using a vibrator is the secret to faster...and multiple...self orgasms. Vibrators offer more strokes per second than hands do. Experiment with your toys to learn what turns you on and how you experience an orgasm.
A curved vibrator may make it easier to hit your G spot. A nub on the tip of a vibe makes it easier to stimulate your G spot. Try using a scooping motion with the toy by dragging it across the front wall of your vagina.
After you discover how to trigger your orgasm this way...you will probably find your G spot is even more responsive and able to trigger screaming orgasms.
Once you've learned to wake up your G spot by yourself...move on to stimulating it with your man inside you.
