"So," Tonya says, "just to get this straight, you're essentially asking to have two 'X' chromosomes, or whatever would be the equivalent, just as you do now, with no changes. You want a 'working' penis, which, for those who have them means, and pardon the graphic terminology, both urination and as a conduit for ejaculation. I would also assume you want it to be a sensitive organ as one that is participatory in sexual congress. It also means it is likely to be a trait you pass along to any children you have with other women, or those you carry, and it further means you can impregnate yourself if you desire, but would then only have female children with yourself or other women. If you are impregnated by a male, you would have about a 50.5% chance of bearing male offspring, which is around the statistical average. While this technically makes you the equivalent of what others would call a hermaphrodite, you'd be entirely and completely female, and would not pass along any added number of chromosomes to offspring. Did I get that entirely right for you?"
"Like you said, perhaps a little graphic, but necessary. That sounds like exactly what I'd want."
"Ok, then, a further detail. You asked for the 'right size' for your penis. Should that mean if you were mounted by, say, your twin, that would be the largest size you could enjoyably accommodate inside you during procreative sex? That also triggers the question of the size of your womb."
"True. I want to be tight, before and after child bearing, deep and easily stimulated so that having sex is a very pleasurable act, and if there is, say, musculature you can add inside to enhance the experience, that would be even better."
Tonya stops and things for a moment. "We can do all of that. I think you're going to be happy with the results. Is there anything else?"
