When I was around 20 years old I went to the gynecologists office for my yearly exam. I was surprised and embarrassed to learn that the new secretary was the secretary from my junior high school. I of course played it cool, not wanting her to know that I was embarrassed to see her in my gynecologist's office.
She was asking me the standard questions that they ask you in a dr's office when she asked me, "what form of birth control do you use?" I told her that I was married and that my husband had a vasectomy and that I did not need birth control.
She said, "Well honey,that doesn't matter, that's him. You still need something to protect yourself."
I was mortified that she could insinuate that I would sleep with someone besides my husband. All I could say to her was, "well it matters to me and I don't need anything else."
I can honestly say I never slept with anyone but my husband for the entire 16 years of our marriage. That includes the 3 year period after I left him and gave him a chance to clean up his act so that we could get back together.
