I masterbated and ejaculated on my hand ✋ then I washed my hand with normal tap water and wiped my hand properly with towel then after 4  hours I met my girlfriend and fingers her between these two acts means in 4 hours I touched many objects like doors ,bikes handle and many more things and my hands are also fully dry and their is no sticky substance on my hand. So my question is that can she become pregnant by this act??
