I get a strange really stick liquid when I 'cum' it doesnt shoot out, just dribbles, but it looks like glue sort of, well, see through glue :P
Not everyone shoots - many of us do only dribble. And when you first start cumming it is often clear until all the glands start working. If it only comes out at orgasm I'd say it is cum; if it comes out slowly while you are aroused it's pre-cum.
Thats what mine does I dont get much if any precum and when I orgasm it just comes out slow, it doesnt shoot. It is alot easier to clean up though. lol
