It may be possible for pregnancy to occur under the circumstance you asked about, but it would be one hell of a longshot. Was there any semen around the vaginal opening? If there was, then maybe. But if the semen was confined to the clitoris, it would be unlikely any sperm would be able to swim down to the vaginal opening without semen also being further down the region. Sperm don't react real well to air. Once inside the vagina, though, it can live for between 3-5 days, though the longer it's in there the weaker it generally becomes.

adviceman49 answered Sunday November 18 2012, 9:43 am: The previous columnist is correct. Anytime semen comes anywhere close to your vagina opening they are capable of swimming in and making their way to an egg if one is there to be fertilized. This is what semen do. While the chances of semen swimming in from outside the vagina are remote it has happened.
Semen is also in a mans precum, the liquid which is meant as a lubricant that is emitted during intercourse prior to ejaculation. It is also emitted while giving a guy a hand job so if you do give one and some gets on your hand keep that hand away from your vagina.
A note for the record here. Precum is not something a male can control or is something they feel being emitted during sex. This is why the pull out method of birth control has almost a 100% failure rate in preventing pregnancy.
When ever having any type of sex with a guy where his penis will be in or near your vagina make sure he is wearing a condom. He won't like it all that much but condoms, when worn correctly, during intercourse are 85% effective in preventing pregnancy. Even if you are on birth control pill make the guy wear a condom. This extra ounce of protection keeps the stork away. [ adviceman49's advice column | Ask adviceman49 A Question ]
