Precum does taste better, it's pretty sweet and pleasant. Imagine if that's all there was to it. Tasting a bit of slippery sweet off the top of his dick. But there's no challenge in that. Anyone can do that. Swallowing his full load, now that's a challenge. That's something to be proud of. I love slurping up his precum, licking it out of his slit and savoring its taste, enjoying the sweetness now because I know any second I'm going to get the real stuff, and it's not as pleasant, it's not as easy to taste, I may even have second thoughts about wanting to taste it, it's like being nervous or anxious about anything in life, but you work up the courage knowing that it's something that you have to do.
I actually prefer semen that isn't always the best tasting. I really enjoy that thick, strong-flavor, salty, maybe even a little bitter tasting load because then there is no question that you're really tasting sperm and only sperm. I'm disappointed when his load is thin or flavorless. There's less of a challenge.
Sperm gives me a purpose and gives me confidence. Some people set life goals or challenge themselves to accomplish something meaningful, but my goals are so pathetic, submissive, yet empowering. Just be brave and eat his load. Swallow all of it no matter how it tastes. You'd do it if you were on Fear Factor and winning 50k wouldnt you? So it's no different then. Challenge yourself to be the best version of you. My dick gets so hard thinking that the best version of me is being a fearless cum swallower. Sucking tons of cocks and eating all of their sperm no matter what.
