Can sperm be washed off by simply washing it with water and hand soap? My gf and I were having oral sex and when i ejaculated, i ejaculated inside her mouth. but then i noticed than maybe a drop of sperm was left on my penis so i removed it with my finger . I washed my hands not that thoroughly but i even used hand soap. then after about 3-5minutes of talking i fingered my gf again i m not sure if my hands were still wet but i would think that they since i always wipe my hands to a towel to dry it off. could there be a chance that my gf be pregnant? because she has been delayed now for 3days though she has been tired from travelling from one state to another. Please help me!!
