i don't know how to orgasm and play with myself

Well... When you are aroused you feel the need to get done with it. That's when you masturbate or have sex (most of the times). Maybe you should think of something to turn you on? Maybe watch a video, think of someone. Whatever you want to get you in the mood and then the process will start. I think the most effective way would be looking at amateur masturbation porn, and just do what they're doing. Depending on what you have down there and if you don't search in those websites for the DEEP stuff, it should be ok. Eventually, the orgasm will come. I hope it helped you out.
