I don't think tasting one's precum is gay. Some guys in real life would get squeamish and say it's gay if they found out, but they've probably done the same thing behind closed doors as well. On the boards we can be honest.
I don't mind wiping precum from my glans and licking it off my fingers. It tastes sweet. If I am masturbating dry, I don't want it to trickle down my shaft anyway, slipping up the works.
It's my semen that tastes salty. I'm not too crazy about that stuff.
