Hi, Thanks for query, Yes it is quiet possible that you have tore your hymen. Hymen can be torn by even cycling,horse riding,long jump etc. it is a common that women gets pregnant by precum. pre-ejaculatory fluid, preseminal fluid, or Cowper s fluid, and colloquially as pre-cum is the clear, colorless, viscous fluid that emits from the urethra of a man s penis when he is sexually aroused. It is similar in composition to semen, but has some significant chemical differences. The presence of sperm in the fluid is debated. Existing research has found none or low levels of sperm in pre-ejaculate, Thanks.
