I was curious but dh and i have been togather for 15 years and i noticed from the first time we had unprotected sex that if i just wiped and went to sleep the next day i have a nasty fishy odor.This never happens with protected sex or if he does not finish.I also dont notice it if we dtd early in the day and im up walking around its really just over night.Could this be a sign that his semen is making my ph jump really high or something?
