Cunnilingus and Pain
I sent this in before but think I may not have actually posted it. My wife says that after about 10 minutes of me going down on her, it painful. She thinks somehow she is having a bit of reaction to the natural chemicals of my mouth. Have you ever heard of anything like this?

Any chance it's your whiskers? I understand razor burn down there may not be pleasant.
Don't think so, I shower beforehand and wash with a non-scented soap to avoid and allergy.
I haven't ever heard of the natural chemicals of the mouth having a painful reaction with the natural chemicals of the vulva. Paul may be right in making sure that you don't have too many whiskers - but for some women, whiskers can actually be pleasurable - so I'm not sure that's it. Does she experience pain when you engage in other sexual activities together? Or is it just cunnilingus? If it isn't specific to cunnilingus, then there might be something else going on here and she should see her gynecologist. If it is specific to cunnilingus, I wonder if she likes it? How does she describe the pain? I'd really like to know more information here, but it might be wise for her to talk to her gynecologist about it.
