I don't mind going to clubs, especially on my own.
I find so long as people allow me to be myself, have a wander around, a chat, a few drinks then a club is a pretty cool place to be, I actually usually go to hear good EDM (not that that's likely to happen)
It's people who are pushy about making me come dancing (usually friends) or have the whole night planned:
"don't do 'X', you'll look like an odd ball"
"let's go 'X'!!!"
"come on it's a club, we're here to 'X'"
is the only downside to going to a nightclub.
