I'm not entirely sure if this is the right place for this, feel free to remove it. I'm not really sure why I'm in this situation, but I'm trying to figure out whether or not I'm the asshole.

I'm at a friend's house for a party (he invited me, and I had never been to this friend's house before, so I was there as a guest). I was invited by the friend to hang out and drink, so I'm not completely sure if I even know his name. Anyway, I'm pretty drunk and chatting with my friend. I know she's a ladyboy (from what I've seen on Youtube/Tumblr).

My friend's boyfriend is also at the party. She's been playing the "I'm not gay" card, but I don't really see the point. All I've heard is "I'm not gay" and "I'm not a lesbian" so I don't really believe anything she's saying.

Anyway, I'm drinking, drinking, and the conversation eventually comes to my friend bringing up her boyfriend. My friend goes on about how her boyfriend is not being her "ladyboy" and that I should accept her boyfriend. I basically told her I don't know what that means, but I know it's pretty stupid to bring up a boyfriend who you just met. I also told her she was being pretty immature with all the "I'm not gay" stuff.

So I don't know if I am the asshole, or the friend. It's like the whole "gay is just a phase" bit; I'm not even sure if I accept or believe that either.

I've never really felt comfortable saying anything about my friend being a girl; so, do I say something? I don't want her to feel like I'm just not her friend, but am I the asshole for not saying anything?

I want to make it clear that I'm not the guy. She knows I'm pretty much over it. I know I am a bit of a perv, but I don't even know what that means.

TL;DR: My friend is a ladyboy, I'm not really sure what she means by "ladyboy", and I don't know how to react to her boyfriend.
