Can't feel pleasure masturbating

It's been 10 years since I've begun my sexual life. I've tried watching porn while doing it, i've tried toys, I've tried everything. I have never ever orgasmed from masturbation (basically me doing something to myself) , it doesn't give me pleasure or even arousal. With partners - it's wonderfull, I'm sensitive, and usually get multiorgasms quickly. But of course there's often a time in life when you don't have a partner, and then there's a huge problem!!!! I can't satisfy myself. Did any of you had the same problem and somehow found a way to solve it? Any tips? PLEASE HELP.
