The first time for me it tasted like a slap in the face. It was horrific and the most disgusting thing I'd ever experienced. But guys just love it so much and you get used to it after a while. I love sucking cock, I love the feeling of power it gives me and I also love doing something a guy really, really likes. Letting him cum in my mouth is like the ultimate thing you can do for a guy and even if it tastes terrible which it does sometimes, it's worth it. I always swallow and if his cum tastes really bad it's the quickest way to get rid of it. I found when I tried to spit it out, it just sticks to your teeth, tongue and the inside of your mouth. When you swallow, the act of swallowing seems to stimulate the creation of saliva which helps to flush it away. A few quick swallows and it's all gone. There's no denying though that a man's cum can be foul tasting, salty, mawkish, sticky and smelly. But like anything you get used to it and now it's nothing to me. I always feel this tremendous feeling of triumph when a man cums in my mouth. It's such a powerful, heady feeling and I freely admit that power has a lot to do with it. The power over a man, to decide when he cums and to make him cum. It's not always possible, depending on the position you are in but I love to see the look on a guys face at that moment he cums and he knows he's cumming in your mouth. If you really love your guy and want to do something incredible for him than this is that thing. Even if you hate the taste of cum, it's a small price to pay. As a 'by the way' kinda thing a guy's diet has a huge effect on his cum. Guys who have a healthy diet usually have much better tasting cum. If your guy's cum tastes and smells really bad force feed him lots of fruit, vegetables and fruit juice and try to keep him away from fatty junk food.
Married bi guy here. I love it when a guy cums in my mouth, as the ladies have mentioned, there is this wonderful spurting of cum into the mouth that you also feel as the cock pulses on he lips. It is so hot, his body tensing, knowing that he will soon shoot his load into my mouth. I love the texture and taste, mmmm and the knowledge that I have brought him to orgasm with my mouth. Really enjoy blowing a guy that does not get it from his wife or tells me that I am better than his wife
Well it's different for different guys, and even then sometimes how much the cum or how hard can be different. It also depends how far into your mouth they are. If they're quite far in I don't really taste it usually, but then it can be hard not to gag. Normally I'd just keep the tip in my mouth when he's cumming so I have more control. You can certainly taste it though when it's like that. If he cums really hard then you can feel it squirting into your mouth, but it's just warm, salty and sticky. If he doesn't shoot much then I often can't feel it, but can taste it. Enough detail for you?
