How to orgasm!?!?!?

I usually get horny quite a lot and I'm single so I masterbate, but I can never orgasm. I don't feel anything fingering so I play with my clit but sometimes it becomes too much and it's so sensitive so I have to stop ... Any advice,could really use the help?? Edit: I usually place my hand under myself and just grind (weird I know) and it feels good for about 40 seconds before I just get tired and the feeling goes away but I'm still wet!? Could use help on this as well haha
