Question for pure bottoms

Hi, a question for pure bottoms out there.

Do you guys really don't get erection while being penetrated? So far all pure bottoms I have encountered wala talagang erection plus they don"t want to cum. When I ask, okay na daw sila. Why?

On the other hand pag versa like me, tigas na tigas while being penetrated and they/we want to get fucked until labasan.

Just curious. 😁
