From experience; cum tastes like either A. Nonexistent B. Lightly salted water C. Heavily Salted spaghetti water if the dude does not take care of himself. It has a watery slime like texture that can change depending on how often he came and how much he hydrates. The best cum flavor I've experienced is Á La Nothing and yes when you're in the moment you can absolutely hallucinate the "sweet" taste of his nut
people can like the taste of cum yk. it's all preferences, and gay men tend to like it more since they often appreciate aspects of "manliness" more than women who are attracted to men. some kinks i notice in gay men that i don't often see in het/bi women: muscle worship, stink/musk kink, pissing, armpit, dick workship (even when, and a lot of times especially when it's dirty/unwashed), ass play. many people have the opinion that men give better head than women, since women worry more about cleanliness/taste (as we should) whereas men like it as unfiltered and raw as it can get. it's up to you to decide if this opinion is true. ofc it's different for every gay man, but there's a trend and it's worth considering.
and you gotta keep in mind the mental/psychological aspect of it all. human bodies are never going to taste and smell like sunshine and rainbows and strawberry shortcake, and sex will always be gross and unhygienic to some degree. what makes it good depends on the attraction and chemistry between you and your partner(s), and when you're able to have that, just about anything can be sexy.
Why do semes have no shame in EATING cum??? LIKE WHAT'S SO GOOD ABOUT IT
