Welcome to HCM
We understand your concerns
I went through your query. You are confused that whether precum has some sperm cells which could make your girl friend pregnant.
Experts are yet to come to a conclusion on this point. Expert opinion differs but there are possibilities that precum contain sperm.
But in your case, it is very difficult to ascertain. Almost 99.99 percentage, the chance of pregnancy
is NIL. But there is still the left over percentage chances.
I hope I am able to clear doubt partially. Available for further queries.
