I would agree with the males being more clingy and affectionate.

I have 2 Ragdolls who are brother and sister. They are both absolutely lovely, but Bailey is very affectionate and DEMANDS lots of cuddles and attention. Cleo loves cuddles too but only when she feels like it and she comes up and asks for cuddles. With Bailey you can just go upto him and he is very willing to let you do anything to him.
