<s>[INST] i had anal sex with my girlfriend yesterday without condom...i just inserted my penis once in her anus..then i took it out as she said it was painful..this was our first encounter..i didnt even ejaculate..are their risks of pregnancy?? should i get her an emergency contraceptive pill to avoid risk,,does this pill have any side effect?? [/INST] Hello, and I hope I can help you today. A woman cannot conceive as a result of anal sex, as only ejaculating in the vagina can connect the sperm with the women egg in her reproductive tract. Therefore, your girlfriend does not need to use emergency contraception for anal sex. However, sexually transmitted infections can be transmitted to her during unprotected anal sex, so I recommend you use a condom with an external lubricant for comfort if you are at risk of transmitting any STDs. I hope I was able to answer your question today and that this information is helpful. Best wishes,  </s>
