When you finally do it, try to keep it inside of you as opposed to pushing it out as is so typical in porn. That mistakenly leads people to assume that's how everyone does it. In my vast experience, it is traditional and commonplace to ejaculate inside the anus and keep the semen inside. Leave it in more than 30 minutes and most of it gets absorbed into the colon/rectum.
My Chuck Daddy loves going both ways only does he fuck me in the ass and breed me but he loves it when I fuck him in the ass and breed him both of us spending the night fucking using each other's cum-filled holes
