<s>[INST] hello, id rather keep my identiy anonymous. but me and my girlfriend started doing things unprotected. and i masturbated and i ejaculated. i cant quite remember wether it went on my fingers. but then i masturbated her. :( were really scared that she might be pregnant :( so could you asnwer me this......Is it possible that she maybe pregnant? and How long does it take for sperm to die in the air? [/INST] Hello, Don't worry your girlfriend will not be pregnant. Sperm need to penetrate inside the vagina well cross to the cervix so just by your fingering she won't be pregnant. Please do protected sex to avoid pregnancy.Outside the body, sperm can survive in semen for up to a few hours because they require precise conditions of warmth and humidity to survive. Sperm die immediately if there is no semen or moist condition. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
