Thank you Steve, Inayat Khan has said if our purpose was purely spiritual we would have no need for physical incarnations. Man is both spiritual and material.
...Here I found the actual quote,
Many people think that the physical has little to do with the spiritual. Why not, they ask, cast the idea of the physical aside in order to be entirely spiritual? If without the physical aspect of our being the purpose of life could be accomplished, the soul would have not taken a physical body and the spirit would not have produced the physical world. A Hindustani poet says, 'If the purpose of creation could have been fulfilled by the angels, who are entirely spiritual, God would not have created man.' That shows that there is a great purpose to be accomplished by what is called the physical body. If the light of God could have shown directly, there would not have been a manifestation such as that of Christ. It was necessary, so to speak, that God should walk on the earth in the physical body. And the conception that the physical body is made of sin, and that this is the lowest aspect of being, will very often prove to be a mistake, for it is through this physical body that the highest and the greatest purpose of life is to be achieved. A person only calls it his physical body in ignorance. Once the knowledge has come to him he begins to look upon it as the sacred temple of God.

Well I came back to a quote you have from Inayat Khan Eric. Thanks, sometimes it takes years to understand the wisdom of a Master and the right experiences we have in life to be receptive to receive them. Sometimes even sexual fantasy can be a prelude to the desire to meditate. It is at times difficult to separate the physical from the spiritual. At those moments the physical can also inspire the astral or spiritual body to practice its discipline. What a wondrous apparatus in the sense that it’s intricacies can never be ignored by making absolute statements about good or bad, while discussing some of its functions such as sex. Which at times, and under the right conditions can be inspiring spiritually speaking as well. Seeing it expressed romantically, helps me understand Brian Wilson when he said that his song ‘Surfer Girl’ was a spiritual song…
