the girl i was with that squirted from penetration, i had no idea that she was squirting for the longest time. i thought she was got really really wet. i would ask her if she came after sex, and she said "cant you tell?" this, being one of my first girlfriends and sexual partners, was curious to me. when she got off me, i was soaking wet where she was. i didnt know about female "ejaculation" yet. turns out she was squirting and i figured she was just really wet.
