I am not sure about your question. You need to give more detail. I will try to guess what you are asking about. If you mean when they are tied together after mating, then do NOT try to separate them. The male's penis is enlarged at that time and would be very painful for both of them if you try to pull them apart. Just hold them together and calm them with gentle words & soothing pats, do not get nervous, stay calm. Pretty soon the male's penis will deflate and then they can withdraw calmly.
