My boyfriend and I engaged in manual sex yesterday. He fingered me first and then I gave him a handjob. He ejaculated and as we were nowhere near water...we just used tissue. Later we both washed our hands. A few hours later he started to finger me again...it was in the same place he ejaculated last time. I am worried about pregnancy. I know and I've read several places that say it is impossible...but I'm still freaking out.
