Wow, my partner and I were literally just talking about this earlier on today. She was saying how she is really surprised that some girls wont swallow their partners cum, while some wont even let their partner cum in their mouth full stop. We often kiss after I have cum in her mouth and we share the cum, and sometimes after I have cum inside her, she gets on top of me and I clean her out with my mouth and then we kiss and share the cum also. Its just a nice little fetish that we find really intimate. I would say though, in defense of your partner, it is an aquired taste that not everyone can bare, but you can try drinking pineapple juice, or even buying "Yummy Cum" from this website, as it gets rid of the saltiness of the cum. Some people have worse cum that others though I have heard.
We were saying that we feel that one of the major points of a blowjob is being able to cum in your partners mouth, as it is possible the most intimate thing you can do for your other half; that by letting your partner cum in your mouth is showing them how close you want to be to them... you want their cum in your mouth, swallowing their bodily fluids. You really cannot get much more intimate than that. We also discussed how by not allowing your partner to cum in your mouth, or swallow your cum, it can make them feel bad about the whole blowjob thing, especially if you make a fuss about the taste afterwards; its like saying how disgusting a part of them is to you, resulting in feeling of self-conciousness and shame. But on the flip side of the coin, if you make your partner feel like you want them to cum in your mouth, it gives them a great feeling of satisfaction, that can be an enormous turn on, and results in a far more pleasurable blow job.
My fiancee also made the comparison that if she wasnt willing to allow me to cum in her mouth, she would never expect me to give her oral. Her reasoning was that when a girl gives a guy a blowjob and the guy comes, you just have the taste of their cum in your mouth for a few seconds, at which point you can swallow it and the taste is gone, its just a bit salty. Where-as when a guy gives a girl oral, he has the taste of their vaginal fluids in their mouth for the whole 10 to 20 minutes while they are doing it, while the taste cannot be compared to cum, it is something that has to be experienced during the entire oral experience. In all, there is a balance.
Our summary that we came to, is that allowing a guy to cum in your mouth and swallowing it is all part of the BlowJob experience. It is the most intimate act your can do with your partner, if you don't partake in watersports (which FYI truely is the most intimate act you can do). Swallowing their cum, is in a way, showing them how much you truely love and care for them, because you are happy having their bodily fluids in your mouth and you arent disgusted by it, but instead turned on by it. It is as close as you can be with your partner, as you are taking something that was once inside them, and swalowing it so it is now inside you. You make your OH feel satisfied and adhored in a way that a blowjob alone cannot do, you make them feel as if they are so amazing, attractive and sexy, that you are turned on by them so much that you must have their cum in your mouth... those are the sort of feeling you give a guy when you allow them to cum in your mouth.
So come on, its just a few ml of liquid, that is slightly salty. It only stays in your mouth for a few moments, you swallow it and its gone. I will say this though. Guys, if you want your Partner to Swallow your cum, you should be willing to swallow it yourself. Cum in your partners mouth and let them snog you with it, simply so you understand what they experience when they do it for you. It might give you a new appreciation for what they do for you.
Peace.
