Before my current partner, I had never experienced an orgasm during sex or even oral sex. My current partner of over two years is great; however, I feel like I take to long....during oral sex lastnight I felt close, then I lost it and started worrying about how long I was taking and got so frustrated that he sensed it, stopped and I burst into tears. He asks me why I can't just lie back and enjoy it and that it doesn't matter - so how can I stop worrying about this?? I've also felt my libido is kinda low lately - what causes this and are there any solutions? Help please.
