I think I figured out what is going on. I read Our Bodies Our Selves in the 70's and have been doing a self gyno exam weekly ever since, checking my cervix, etc. I checked last night and everything feels exactly like it always has. I think I may be sensitive to latex. Perhaps I was "immune" or accustomed to it before, because I had sex with condoms all the time. Now that I've been celibate for so long, my body is reacting like it's foreign matter and rejecting it.
