I think I might be immune to mono. I have been exposed to it over, and over, and over. I was exposed to it just last month.
I was thinking about this, and remembered a time when I got vaginosis. The doctor said that the cause was a pH imbalance, but I know the imbalance came from a sex act. The partner in question also walked away with urethritis for the same reason. I guess we rubbed each other the wrong way. I was never the same taste or scent after that incident. I guess that counts as a STI. That was my only partner with whom I had unprotected sex (not counting when I lost my virginity). We were monogamous for six years, but at that point, we'd both moved on, and it was just a terrible mistake on many levels. Petite, the doctor I saw because of the itching was such a bastard! He tried very, very , very hard to make me feel low because I had four partners in a six month period. As if it's my fault he's too small and ugly (inside and out) to get as many partners as he truly wants.
closetbi, I agree with you 100%. So does my husband. Those co-workers have never been welcome in our home as a result.
