The only cum I don't like is from regular tobacco smokers. Other than that it does indeed range quite a bit, from sweet, to salty, to chlorine and I enjoy the variety. Some guys have cum that is a little astringent, kind of like Vicks without the eucalyptus. I like the way it leaves my lips a little numb, like I've taken cocaine (which hasn't happened for a very long time). But I do associate cum with mind-altering drugs. Maybe it's packed with hormones or endorphins or something. It definitely gives me a buzz anyway.
