Oh dear, you say you could easily make love to her 3 times a night! I think it's you who needs the help, not her! I think you are being very selfish and disrespectful. Apart from the probable emtional aspect of her feeling you just want her for her body, many women simply can't physically cope with constant bombardment in that area of their bodies! We're not all prostitutes, you know!
I would suggest you back off - which you will do, if you genuinely love her . Show her that having a cuddle or holding hands is enough sometimes. She needs to be loved for herself, not for her body.
If you're not grown up enough to figure things out for yourself my friend, I would suggest you read 'Men are from Mars, Woment are from Venus'; an informative read for both sexes.
