I am 21 with 2 kids and I have never had an orgasm

I don't blame you. When would you have time to have one?

PS - If you all ever get any time alone... relax and play. With a vibrator... with hands... with fantasy... it's a turn on to talk and communicate in bed... and helps a woman suspend her daily self and feel something new.
-Do you all talk in bed?
-Do you take your rime?

It actually sounds normal - many girls have trouble "O"ing when young - under 25.MSo, relax, you are normal... And busy!

Whαt kind of orgαsm clitorαl or inner?

EVER? As in not even with yourself?-I need some clarity, before I can advise you further

Get some toys and relax, get the kids out the house and enjoy yourself.
