foreword: i think the answer to my question might be on the rooshvforum but for some reason my IP is banned (i live in a dorm) http://www.rooshvforum.com/thread-33854.html

here's what happened

i banged this broad a few times and then stopped seeing her today 2 months later we bang again, lots of LMR but once she's in bed and comfortable she can't wait to be naked. going hard as fuck, she's grabbing on to me and kissing, suddenly I notice she has tears going down her face... stop pumping and calmly ask her if she's alright, she says "yes, it just happens sometimes" (it never happened the previous times we had sex) we continue until i finish

has this happened to anyone before? what does this mean?
