If you were a woman, who wanted to be a man, could you get a penis? And once you got your penis, could you masturbate, ejaculate, and experience other male sexual behaviors?

And vice versa. If you were a man, who wanted to be a woman, could you then get your penis removed, and then masturbate?

I have been with my long term girlfriend for five years. I am seriously thinking about getting engaged.

Over the last three years she has taken control of our sex life. I have definitely become submissive in the bedroom. We don’t get into BDSM, but she always decides when, where, and how. She loves this control. While I have come to accept my submissive role, and I do certainly enjoy making love to her and pleasing her, I have asked her on many occasions for some variety. I would like to enter her sometimes and she has not performed oral sex on me for years. Granted, I am a bit under average in the endowment area and she always has a hard time reaching orgasm with straight intercourse. I have tried to talk to her, but she always shuts down the convo by making me admit that I love pleasuring her. Of course when we start fooling around I am so excited that I just follow her lead.

Honestly, I am very happy in every other aspect and I don't want to add any friction to the relationship. She is a very private person and doesn’t like to talk sex. Visiting a therapist is not an option as I have already subtly suggested it and been rebuffed. Should I be overly concerned? Should I continue to press the issue (although it doesn’t seem to be getting me anywhere) or just accept my role? Again, I do enjoy pleasing her and I usually get off. I guess I could be happy continuing this way and I don't want to lose her. I would love your thoughts.
