My girlfriend likes when I ejaculate in her vagina but during oral sex she moves away when I tell her I am ready to climax. I ejaculate onto my belly and then she gets up and throws me a small towel. I do not understand why it is okay in her vagina but not her mouth, but I am not going to challenge her on this detail. I am just happy that we are in our late 60s and have a very active sex life.
