Ok here's an idea. STOP MASTURBATING. You know jerking off doesn't give you any satisfaction, it's like saying you should smoke more to battle your nicotine addiction. If you stop jerking off, your sex-drive dies down, you'll stop being frustrated and anxious about your lack of sex, you will be able to socialise with women in a more casual and laid-back manner, which really cuts back on the nervousness. This will make you more attractive in their eyes and eventually you might get hooked up with someone nice. In the meantime though you should not think about it, just lay it away and concentrate on other stuff and what you want will come to you eventually, while you totally do not bother and may feel at ease.

But ofcourse this doesn't help if you don't also stop thinking about sex. It's really not as impossible as it sounds, just a matter of will.

But if you want to drive yourself mad, do it your way.
