Masturbation

So, I’m 17 and I’ve had sex a few times before. I don’t think i’ve ever orgasmed, it’s never really been all that great for me pleasure wise. Recently I’ve been trying to masturbate to see if that will do something for me, and though it feels good, I can never bring myself to orgasm. Is this normal? When I only do clitoral, i feel that it is to intense for me to finish. Any recommendations on how I can bring myself to cum?
