I've HEARD males are more laid back - but I have girls so I can't say.
I will say this - I get bombarded with kisses everyday and they don't leave my side for even a minute. They're VERY VERY attached and cuddly.

Cheri sleeps on my head/pillow at night and Chanel is by my side - they don't even sleep in one of the 4 baby beds they have. Where ever I am - so are they.
Even when they were small - both girls just seemed to always be velcro'd to my butt.
