My wife had an orchiectomy, so she doesn't have the boys anymore, just the shaft. since the testosterone is gone, it doesn't act like a boypenis anymore. I call it a girlpenis sometimes, but generally we refer to it as her clit that is just larger than normal.
we do occasionally have hetero-sex with me on top, but the way I grind into her, she imagines as if I'm the one with a strap on and it gives her the most delicious orgasms. otherwise I'll use a strap-on for anal with her, or we just play with the vibrators. but the way we have sex is very lesbian, so she usually doesn't have any dysphoria problems.
