NO...no more than a woman feels you cum... When he cums tho, if you have experienced it before, you will know. All tend to thrust as deep as possible, when the load is being delivered, you should feel that explosion as he thrust his hips into you, an then you will feel the fullness go away quickly, his penis will lose erection quickly. The fluid delivered will not be what you feel, the thrusting to deliver it deeply, will be how you know. Usually there is a moaning and groaning, and you will feel the cum dripping out of you if you stand up. I prefer to reinsert the Butt plug, to hold on, butt not always. Sometimes they run to the door, and I like that dripping occurring as I let them out.
