I have 3 SV males. F3, F4, and F5. I don't know much, but I do know that every cat is different, and our 3 boys vary in the amount of affection they bestow and when they bestow it.
I've never had a female.
I have an F4 boy who is so cuddly he literally throws himself into our arms when we are on the couch or in bed, flips over on his back and snuggles with his head under your chin, or wants to be held and snuggled like a teddy bear while he kneads. Usually one after the other. Our F5 boy likes to lay next to me or on top of me, and hold my hand between his paws. He frequently asks to be picked up and carried (by jumping at you- he expects you to put your arms out and catch him). If you ignore, he will jump on your shoulders.
Our F3 boy is least snuggly. He likes to be with us, and cuddles on the couch and in bed, but he doesn't display affection the same way the other two do. He is however always at the door meeting us when we get home, and we get a head butt when we walk in the door from him, and if you are in my house and sick, he is the boy who is glued to you purring up a storm and trying to groom you.
