Has your partner expressed a problem with your increased wetness during intercourse? This is oftentimes a welcomed problem. Since swab results were negative, did the doctor suggest to you that this is normal vaginal secretions?
I am thinking that you went to a gynecologist for the check- up, and that he did an internal exam to determine that there are no other findings such as vaginal prolapse, which would give your partner the sensation that he has expressed. Hormonal levels change with your menstrual cycle but what you describe is not related to low pituitary levels and then tests came out okay, anyway. Please look at the website below with suggestions for reducing vaginal wetness.
