Is it normal i can't orgasm

There's nothing wrong with you.

Take it slow. It's not a race.

Set aside some time to relax, have a bath, light some candles, use a few drops of lube and just play.

It is a combination of some clitoral and some putting pressure just inside the vagina about two finger joints in and moving your finger as if beckoning someone closer to you a fuller bladder even very full will help this as it makes that area stick out and be hard /sensitive . Other bonus is after action letting out distended bladder will feel extremely good and bladder will super empty . Plus is getting these feeling when full will make skipping the ladies on the way to see your man so you are already full you will be already building up syching yourself for the fun to be so a sort of extended for play some nice new panties for man to discover and appreciate may add to the unwrapping fun as well . Not saying to wet or make a mess just saying to have fun enjoy yourself

You are doing it wrong! Rubbing belly button rarely gets you off.

That's life. Deal with it.
