What happened then? Were you pregnant?
The chances of you getting pregnant from pre-*** are virtually none.
Because pre-*** doesn't contain sperm by itself. It only contains sperm if it was picked up from the last ejaculation (e.g if the guy ejaculated and didn't pee after).
And, if you don't want to get pregnant, ALWAYS use protection. If you are on birth control, you should be fine, but even with me on bc, we still use a condom as a backup method. Its your body. Tell the guy to use a condom if you feel you should.
