One day I met with my gf and we don't have penetrative sex but at the same day in the morning I masturbated and ejaculated in the underwear and we both met after 12 hours from masturbation and sperm gets totally dry in my underwear. So my question is that if I touches that dry sperm on my underwear and fingered my gf can she become
pregnant by this act? We don't have vaginal sex, penetrative sex, not even touches my penis before fingering?
