Here in Portsmouth they have clubs that put on gay nights. Although they do have a gay club and a gay pub or two. But yeah, perhaps in Lincoln they have clubs that put on gay nights. Also, I can guarantee that there is at least one other gay person at Lincoln uni - friend of mine. But it's a bit silly going around asking if there are any gay people in the uni, they don't go around with neon signs on their forehead.
Well, not all of them. :P
