"I mention my race because not being Caucasian has given me an advantage. These girls are smart enough to know what the white blokes want, but with me they were a little more curious, open and adventurous. This contributed to my experience."

Good on you - I bet they have never seen a man of mixed race before - I'm sure they,being smart, having Tertiary qualifications, thought you could not be like all those other white blokes who just wanted to fuck them.
How were they curious?
Open - you mean willing to open their legs for you?
Adventurous - you mean were open to 3 holers, 3 sums and water sports.
