For the second time I have possibly ejaculated but I'm not sure because it smells like pee.

Well I think you actually already know the answer to this one..
Female ejaculate is reportedly odorless.

Female ejaculation does not smell like pee, it is clear and doesn't smell. You are most likely peeing, but plenty of girls do, so it's really not anything to be ashamed of.

Very little is known about female ejaculation, but it is led to believe that it contains about 5% urine. I've also heard that the smell and taste has something to do with your diet, so if you eat a lot of fruits, it will be sweeter and smell sweeter. You are not peeing during sex. You are simply ejaculating and the slight odor is completely normal and something all girls smell. The odor will not stay for long and the stains on the bed should dry clear. If you have any concerns, just as your gyno, as I am sure they'd be happy to help. Also, you should pee before sex, but especially after, in order to avoid a urinary tract infection. Don't be embarrassed - it's a normal thing - and girls deserve to feel just as good as guys! Male ejaculation has it's own odor, so don't worry! I hope this helps!
