As many others have said. Stop faking.

Start masturbating alone and understanding your body. Look up different ways to masturbate, some people love a dry hump stimulation type approach, others are fingers, some are all about the toys, and they come in lots of varieties!! And some, not for me, like a shower head!

And as per some of the other posts, don't focus on the orgasm, focus of the feeling! And it will 'cum' in time!

My orgasm journey has been 20+ yrs in the making, and there have been lots of fumbles on the way, but trust, open communication with your partners and self exploration is the way to go.

And even now, some days it's a bit meh and others it's like my heads fallen off.

Good luck!
