Unlikely But..: If your partner had semen on his finger that was stimulating your clittoris then it would be possible for sperm to have entered your vagina. The number would likely would have been very low. The negative pregnancy test would indicate you are not pregnant. Is your period delayed?

Should be fine: If you are going to have adult sex play, then must consider who's got the sperm and where + where might it get insimenated? Mistakes in this game give you diseases that might last a lifetime, or unintended oppspring.
