I had planned to go with a couple of friends and I asked him if he  wanted to join us, he told me I couldn't go because he had already planned to go the same night and if I went he won't be able to be "him self".

We are fraternal twins,18, both M, both gay. we have Been to many  parties and clubs together and it was never an issue nor he ever brought it up. The only difference in this case it's we are going to a gay club for the first time.

I know that he has never kissed someone in public, he had boyfriend at one time but, back then they were both in the closet, so every thing was very secretive. I'm pretty sure that's what he is worried about.

AITA here ??, I understand that he might feel like he is being observed if I go, but I'm gay too it's not like I'm going to make fun of him.
