My girlfriend and I were having sex, and I wore a condom. We were going for 5 minutes at the maximum, and I did NOT ejaculate. The condom was on the whole time and it was not torn or anything. I looked down there when we were done and there was white creamy substance on her genitals, looked exactly like sperm. That would be impossible though because I didn't even release anything, plus if I did it would've been in the condom. What was this and was it from her? I am a little worried please help thanks!
