Girls intention? Is this acceptable in this type of situation?

Anonymous
So, this one night me and this girl really vibed well, so I asked her if she wanted to go make out, and then she lead me to the bathroom, it was quite busy and occupied by girls, I mean it is a public bathroom by the club, and my date, well, she made it clear to the other girls I'm there for her.

I felt a little embarrassed because I never ever went in a girl's bathroom before. And secondly, I felt like I was intruding, though I had no intentions of causing any discomfort or make the girls uncomfortable, though I was never in this situation before... So for the guys, would you go in or stay outside? And for the girls, is this acceptable between girls to take a guy in the bathroom?
