Hello, I have gone through your query and understand your concern. The risk of HIV transmission through spit for lubrication is much less than that from anal or vaginal sex but it is not zero. It is not necessary to get ejaculate to get infections. But you are at high risk of Sexually transmitted Infections like herpes, syphilis, gonorrhea, genital warts (human papillomavirus, or HPV). Actually it hard to measure the exact risk because you had vaginal intercourse with her. Thus look for any symptoms of sexually transmitted infections like rashes, blisters, itching, discharge, fever, burning sensation while passing urine. If you encounter any of these symptoms, then you need your Primary care physician advice and treatment. Hope this helps. Please write back for further queries. Wishing you good health.
