Will sperm leak out of the condom?

I was having sex with my girlfriend, she was on top of me and i ejaculated, she was still on top of me for about 20 seconds then i told her to get off, i felt my penis and the outside of my condom was wet and slimy. Is this my sperm or is this the girls vaginal fluid?

it could be either or. if you're worried ask her to take plan b within 72 hours of the sexual encounter.

Was the condom broken when you took it off?  Or was it intact?  

The outside of your condom will be wet and slimy because of the woman's vaginal area is wet.  Your sperm should be at the other end of the condom.  You might have felt the sperm coming back down your shaft.

Also becareful with plan b or the day after pill.  Those can be harmful to the system if taken to often.
