IMO, taste has little to do with it. For me, it was first, getting over the idea of "swallowing" (which, when I was in HS was equated with being "loose" for some ridiculous reason) and also the texture. I actually choose my food, and my likes and dislikes more from texture than taste.
I didn't swallow for YEARS. I don't really know why. The idea of it, (although I always loved giving head) the texture, something. A few years ago, or less, My Man said he swallowed MY juices when he went down on me, which I had NO idea he did, and suddenly, swallowing didn't seem like such a big deal.
He'd asked me to do it for years, and I'd just kinda hold it in my mouth and discreetly deposit it in a tissue. NO running to the bathroom for me, that would be insulting, IMO. Once it was over, he didn't seem to care. Ejaculate doesn't bother me in any way. When he comes ON me I can lie there for half an hour with it slowly liquefying, he's the one who grabs the Kleenex and cleans it up. He says "It'll find it's way to your egg and then we'll have to deal with an other kid." UM, from a Pearl Necklace? Highly doubtful. It'll seep through my belly from osmosis and impregnate me? He's so funny.
Anyway, one day, I was just so turned on, had just had a mess of beautiful orgasms, was coming again just from going down on my beautiful Man and he Came without warning and it went down. I was so proud of myself, after years of "not being able to do it" (yet doing things a lot more "advanced" IMO) Now, it just depends on my mood, if he asks me, if we're somewhere that it would be more convenient, like sometimes he comes last, and all I want to do is go to sleep and am too lazy to even reach the headboard and get a Kleenex, I'll just dispose of it orally. *SHRUG*
