Lisa, it does not mean anything. Sometimes your partner will ejaculate very little. Men does not produce the same amount of ejaculate every time.
His semen will turn to a watery clear fluid and after a few minutes this fluid can flow out quickly or just ooze out over a long period of time making you feel wet and your panties dirty.
If you orgasm after he ejaculated, your cervix can suck up more of the semen that at other times, especially when you are fertile.
If you are not trying to get pregnant, PLEASE stop having intercourse without taking precautions (the pill and/or condoms). Anything less than this will put you at risk for getting pregnant. Condoms will also protect you from nasty infections and STDs.
Not to freak you out, but I had this happen to me 2 months ago. We got our signals crossed, he thought it was safe and it wasn't - he came inside me, and it did not come back out. I believe it was because I was ovulating at the time and my cervix was low and open - optimal conception mode.... I tried squeezing it out, douching it out and then I went and got Plan B. Unfortunately - I became pregnant.
Men does not always ejaculate the same amount. This is especially true if they ejaculate often, for example, if he masturbated shortly before, or you gave him a hand job or oral sex, he might ejaculate just a little bit.
Some men will also fake orgasm when they take too long to ejaculate.Most men admit to faking orgasms when asked.
Whatever the reason is, your vagina is sealed. Everything except sperm will come right out again. Some sperm can swim on their own and will go up your cervix. Semen is just a fluid, and it cannot swim. So the only way out is through the vaginal entrance.
