I am starting to think my girlfriend might be transgender.

We are very active sexually but she always wants me to penetrate her rectum and not her vagina. That just seems odd. A real woman would want it in the vagina mostly. I asked her, but she acted offended. What is a way I can tell if she is really trans or not? I am not gay and I don't want to penetrate any men who are pretending to be women. That is just gross. It is a real violation if she really turns out to be male. I really need help with this on guys. Thanks in advance.

Take her into a shoe store. If she buys twenty pairs of shoes than definitely a woman.

I didn't know they made inflatable trans women.

You beat me to the punch, you douchebag.
