...to change the taste of semen?

I've read the advice to drink pineapple juice to make semen taste 'better'...better than...?? Just a joke...I've also read that spicy foods will make semen taste bad.

So...how long does it take to 'purify' after having spicy foods out of my system?

If my semen tastes even remotely like some of the sandwiches that I eat I sure don't want my lover to share in those delights. The experience of eating spicy foods is optional for me, I don't want to make it mandatory for my lover.
