Okay so weird question.
Maybe a bit TMI.

Is it possible to have a reaction to your partner's semen only during pregnancy? This never happened before I got pregnant but during this last trimester and some of the second, everytime we'd have sex, I would get all irritated and swollen afterward. And my nether region kinda burns. It's not the act of sex that does it, I feel fine during, it's only after he climaxes. I have to immediately go into the bathroom and wash it out or it continues to irritate me.
