Asparagus cum is the worst.  :puke:

YES, diet does affect cum taste.

Yes I've heard. Luckely I've never encountered it and hopefully it stays that way. The same goes with urine. What an awful smell!

if your answer is no, which i think it is, then it is not your partners fault since there is nothing wrong with him.

YES, diet does affect cum taste.

How you like cum and its smell and you get nausea?
Is it just with him then?
I don't think his diet matters. I think it's chemistry!! Believe it or not.
However, I would never have or give blowjob with flavored condoms. I'd rather not do it at all!

The average person (at least who I've encounterd) has sperm that smells and tastes fine because of the variation in what he eats and drinks. When you drink a lot of beer, soda's (like Pepsi, Sprite, Fanta), energy drinks, coffee and tea, your sperm will going to taste bitter. Eat more fresh sweet fruit and a variation of vegetables (no the bitter ones) and your sperm will taste sweeter in time. It depends on various factors how long it will take. Think of how many times you cum, the amount of change in you diet, your bodyshape/metabolism and other bad habbits like smoking.

@buonaroti, I have the exact same issue with you. The glans hurts and I find the feeling annoying so I ask them to stop as well, which is bad, given that blowjob is something they've been thinking about and I hate it that I can't give them the pleasure. I also need my foreskin to be able to enjoy it. I am not sure what to do either, I think we need to force it on ourselves until we become less sensitive - my assumption (for me at least) is that I have monthly periods of sex abstinence and this is why I get so sensitive. I believe when you accidentally get out of his anus, you have a hard time putting it back in as well, if your foreskin is 'down', right?
I'd like to see others' opinion on the matter.

For how long have you tried it to "adjust" to sperm and is he the first guy you've tasted? I know that in the beginning I've had the same problem. I still don't like the taste of cum but it doesn't give me nausea anymore. The taste of semen is also given regulated of what you eat. You could try a diet for him. Search on the net for what helps and what doesn't.

As for your sensitive penis; It's great that he likes to play with your penis and wants you to enjoy it. He only needs to take it more slowly so it feels more comfortable for you. The sensitivity will wear off in time because you develope a bit "callus" over time and you get used to the feeling.

Don't force anything is the keyword and you can always rely on YORCH32's tip!
