I have performed oral sex on folks with a dick a few times, I've learned how to deepthroat and I enjoy it a lot though I'm still practicing – a perk used to be not tasting cum as much cause it's just already down my throat etc. But with my current partner, despite their diet not being anything great, their semen is… Very mild in taste? Oddly good?? Especially in comparison to everyone else I've tasted.
My friends say that all the cum they've tasted has never been mild in flavor or even something they'd think tatses good, so… Idk.
