My physical type I would say is pretty petite blue or green-eyed blondes - around 5'2/5'3, size 8-10. Tight little bodies, great butts, perky natural boobs - bust size not really important. Girl-next-door pretty is fine, but I'll settle for stunning.
My two favourite regulars fit the bill almost exactly (one has enhanced boobs but a fantastic boob job).
But I'd say the physical type is less important than the attitude / services on the whole - I've had a great time with various ladies ranging from size 6 to 16, never gone beyond 5'8 tall (and probably never would), hair colour not an issue, big boobs, small boobs, real/enhanced, all good.
I'm more interested in ticking items off my sexual bucket list, so it's more finding a good match in terms of services offered.
I would like to shag my way around various ethnicities just to say I have - seen one black lady and one Brazilian so far - so at some point would like to try others at some point but certainly not my priority.
