Can I ask my trans girlfriend to top me?
What does "top me" mean?
I want her to penetrate me with her dick.
You're free to do as you please with your sexual partner. I don't need to know this information, though.
I think you're a prude.
I'm not a prude, just letting you know that you're free to do whatever you want with your sexual partner. I just don't need to know the details!
