Getting Your Partner to Talk About Being Asexual and Being Hypersexual

My partner considers herself asexual while I consider myself hypersexual. How can I help train my wife to replicate that in ways that are minimal for her having to keep my whole dick in her mouth for a long time? You know what I mean? So there's always ways around it. And yeah, that should help. All right. Next question. My girlfriend doesn't want premarital sex. Only four play is allowed, but I can't control after four play. It's been two years. Wow, OK.
