Insert a buttplug and keep his semen so long that it dissolves into your body through the anal channel walls.....as it dissolves , it becomes part of your own body nd remains, in one sense or snother, as part of you....in a way like being impregnated, a homosexual pregnancy as the seed enters into your whole body system and remains as [art of you.
You are right. My first top daddy who was a 70 yr old man would not allow me to go the bathroom after he had cummed inside my hole. He would hug me tightly in bed after cumming and would kiss me and engage in after play.
