Quoting Viv, Ev & Gwen ♥:" idk, definitely doesn't sound normal. Maybe he ate something that is irritating to you? Diets change the makeup of cum."
Quoting Kelly-Ann Louise:" I get the same problem. Might be a bladder infection, or you could just be sensitive to his cum? My fiance gets really offended when I tell him his cum Burns me Its only started about 3 weeks ago."Really? How silly lol.
