I doubt there is a trick. I remember a geisha movie, where they teach the ladies to address all manner of gross scents in the expectation of having to deal with those found in sex, like smelling rotten soup or something abhorrent like that, and eventually nothing seems to bother them. After all, I am sure there were gross scents coming from feudal Samurais’ intimates.

Anyway, like you I have my limits and qualities that simply turn me off and when I encounter those, I am done. I never take it personally, it is a state of humanity, but insofar as engaging in sex, unless a shower can be negotiated without notice, the subject is changed. But, this is not true exactly. Of all the women I have loved, no matter what happened, it never changed how I felt about them or deterred me from having sex. The one I loved the most, never smelled of anything. The second one, only slightly, the third one was uncomfortable with herself once, but that was fixed with a shower. In general, in these cases, bacteria is just a natural fact, easily remedied. Sometimes, I could smell my own breath on their bodies that was probably grosser than anything they ever did. We compare ourselves to food. If it doesn’t smell good, we probably shouldn’t eat it. In your case I understand the grossness of sperm. There is nothing wrong with you and I am sure your honey only wants you to be happy, so spill the beans and stay away from it save those geisha lessons.

Oh, and there is one thing I forgot to mention, some things do not taste like they smell, like stinky cheese. If you pair stinky cheese with grapes, you would be in heaven, and sardines cooked Mediterranean or Moroccan style can blow your mind. Morel mushrooms, truffles might smell of dirt or ass, but in your mouth having been caramelized with wine, butter or a red wine reduction, they meld the symptoms of reality with fantasy. There is no expectation or demand that sperm is on your menu. In love, you get to choose what you love and hate. In love, you should be at your safest and happiest.
