i have something to contribute!
last night, my wife and i were really going at it. it was one of those nights where the sex was just awesome. we had sex, i came in her, then i was licking her out and she squirted pretty big. so, after we just rested in bed for a few mintues, enjoying the afterglow and 20 mintures later we started again. same thing, i came in her and i licked her out and omg. a huge gush like ive never seen. it was impressive.
but my point i was gonna make. when she squirted the 1st time, it was a good amount and it was warm and clear and odorless (like usual), but by the time we started having sex again (20 mins later) i did notice a slight urine scent. her cum is odorless at first but gets a scent a little later so thats what you were probably smelling, 7inches. all i know is its not pee, but if it sits for a little bit, it does smell a little. (not that i mind or anything) and when i looked at the sheets so see all our cum, it wasnt yellow or anything. just wet and colourless.
just something interesting.
